To solve this problem, we need to iterate through each number in the input list and check three conditions:
1. The number must be strictly greater than 10.
2. We need to extract the first and last digits of the number. Since the input can contain negative numbers (though the "greater than 10" condition effectively filters out most negatives, it's safer to handle the absolute value for digit extraction), we treat the number as a string or use math to find the digits.
3. Both the first and last digits must be odd (1, 3, 5, 7, or 9).

Complexity:
- Time: O(n * k) where n is the number of elements and k is the number of digits (very small).
- Space: O(1) as we only use a counter.

```python
def specialFilter(nums):
    """Write a function that takes an array of numbers as input and returns
    the number of elements in the array that are greater than 10 and both
    first and last digits of a number are odd (1, 3, 5, 7, 9).
    For example:
    specialFilter([15, -73, 14, -15]) => 1
    specialFilter([33, -2, -3, 45, 21, 109]) => 2
    """
    count = 0
    for num in nums:
        if num > 10:
            # Convert to string to easily access first and last digits
            # We use abs() just in case, though num > 10 implies positive
            s = str(abs(num))
            first_digit = int(s[0])
            last_digit = int(s[-1])

            if first_digit % 2 != 0 and last_digit % 2 != 0:
                count += 1
    return count
```


To solve this problem, we first need to understand the properties of the sequence $a[i] = i^2 - i + 1$ modulo 3.
1. If $i \equiv 0 \pmod 3$, then $a[i] \equiv 0^2 - 0 + 1 \equiv 1 \pmod 3$.
2. If $i \equiv 1 \pmod 3$, then $a[i] \equiv 1^2 - 1 + 1 \equiv 1 \pmod 3$.
3. If $i \equiv 2 \pmod 3$, then $a[i] \equiv 2^2 - 2 + 1 \equiv 4 - 2 + 1 \equiv 3 \equiv 0 \pmod 3$.

So, for any $i$, $a[i] \pmod 3$ is either 0 or 1. Specifically:
- $a[i] \equiv 0 \pmod 3$ when $i \equiv 2 \pmod 3$.
- $a[i] \equiv 1 \pmod 3$ when $i \equiv 0, 1 \pmod 3$.

We need to find the number of triples $(a[i], a[j], a[k])$ such that $a[i] + a[j] + a[k] \equiv 0 \pmod 3$.
Let $c_0$ be the count of elements in $a$ such that $a[i] \equiv 0 \pmod 3$, and $c_1$ be the count of elements such that $a[i] \equiv 1 \pmod 3$.
Since there are no elements where $a[i] \equiv 2 \pmod 3$, the sum $a[i] + a[j] + a[k] \pmod 3$ can only be 0 if:
1. All three elements are $\equiv 0 \pmod 3$ (Sum: $0+0+0=0$).
2. All three elements are $\equiv 1 \pmod 3$ (Sum: $1+1+1=3 \equiv 0$).
3. One element is $\equiv 0 \pmod 3$ and two elements are $\equiv 1 \pmod 3$ (Sum: $0+1+1=2 \neq 0$).
4. Two elements are $\equiv 0 \pmod 3$ and one element is $\equiv 1 \pmod 3$ (Sum: $0+0+1=1 \neq 0$).

Thus, the total number of triples is $\binom{c_0}{3} + \binom{c_1}{3}$.

To solve this problem, I will define a list of planets in their correct order from the Sun. I will then determine the indices of the two input planets. If either planet is invalid, I will return an empty tuple. To handle cases where the first planet is further from the Sun than the second (e.g., "Earth" to "Mercury"), I will identify the range between the minimum and maximum indices of the two planets, excluding the endpoints themselves.

```python
def bf(planet1, planet2):
    '''
    There are eight planets in our solar system: the closerst to the Sun
    is Mercury, the next one is Venus, then Earth, Mars, Jupiter, Saturn,
    Uranus, Neptune.

    The function should return a tuple containing all planets whose orbits are
    located between the orbit of planet1 and the orbit of planet2, sorted by
    the proximity to the sun.
    The function should return an empty tuple if planet1 or planet2
    are not correct planet names.
    Examples
    bf("Jupiter", "Neptune") ==> ("Saturn", "Uranus")
    bf("Earth", "Mercury") ==> ("Venus")

    if planet1 not in planets or planet2 not in planets:
        return ()

    idx1 = planets.index(planet1)
    idx2 = planets.index(planet2)

    # Determine the start and end indices for the range
    start = min(idx1, idx2)
    end = max(idx1, idx2)

    # Extract planets strictly between the two indices

To solve this problem, I will first filter the input list to keep only strings with an even length. Then, I will sort the resulting list using a custom key. The primary sorting criterion is the length of the string, and the secondary criterion (for ties in length) is the alphabetical order of the strings.

```python
def sorted_list_sum(lst):
    """Write a function that accepts a list of strings as a parameter,
    deletes the strings that have odd lengths from it,
    and returns the resulted list with a sorted order,

    and it may contain duplicates.
    The order of the list should be ascending by length of each word, and you
    should return the list sorted by that rule.
    If two words have the same length, sort the list alphabetically.
    The function should return a list of strings in sorted order.
    You may assume that all words will have the same length.

    assert list_sort(["ab", "a", "aaa", "cd"]) => ["ab", "cd"]
    """
    # Filter out strings with odd lengths
    even_length_strings = [s for s in lst if len(s) % 2 == 0]

    # Sort by length first, then alphabetically
    # Python's sort is stable, but using a tuple (len(s), s)

To solve this, I need to implement a primality test for the integer `n`. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. The most efficient basic approach is to check for divisibility up to the square root of `n`. If `n` is prime, the function returns `x`; otherwise, it returns `y`.

Complexity:
- Time: $O(\sqrt{n})$ for the primality test.
- Space: $O(1)$.

```python
import math

def x_or_y(n, x, y):
    """A simple program which should return the value of x if n is
    a prime number and should return the value of y otherwise.

        return y

    # Check divisors from 5 up to sqrt(n)
    # Primes are of the form 6k +/- 1
    for i in range(5, int(math.sqrt(n)) + 1, 6):
        if n % i == 0 or n % (i + 2) == 0:

The problem asks to sum the squares of odd integers from a list, while ignoring negative numbers and non-integers.

**Reasoning:**
1.  **Input Handling:** Iterate through each element in the input list.
2.  **Filtering:**
    *   Check if the element is an integer (using `isinstance(x, int)`). Note: `bool` is a subclass of `int` in Python, but usually, in these contexts, we treat them as integers or filter them out. Given the prompt, standard integer checks suffice.
    *   Check if the number is non-negative (greater than or equal to 0).
    *   Check if the number is odd (using `x % 2 != 0`).
3.  **Calculation:** If an element passes all filters, square it and add it to a running total.
4.  **Edge Cases:** Empty lists or lists with no valid odd integers should return 0.

**Complexity:**
*   Time Complexity: $O(n)$, where $n$ is the length of the list.
*   Space Complexity: $O(1)$ as we only store the running sum.

```python
def double_the_difference(lst):
    '''

    in the list that are odd. Ignore numbers that are negative or not integers.

    double_the_difference([1, 3, 2, 0]) == 1 + 9 + 0 + 0 = 10
    double_the_difference([-1, -2, 0]) == 0
    double_the_difference([9, -2]) == 81
    double_the_difference([0]) == 0

    If the input list is empty, return 0.
    '''
    total_sum = 0
    for item in lst:

To solve this problem, we need to iterate through both lists simultaneously. For each pair of elements (score and guess) at the same index, we calculate the absolute difference between them. The `abs()` function in Python is perfect for this as it ensures the result is non-negative regardless of whether the guess was higher or lower than the score. We can use a list comprehension to construct the resulting list efficiently.

Complexity:
- Time Complexity: O(n), where n is the length of the input lists, as we iterate through the lists once.
- Space Complexity: O(n) to store and return the list of differences.

```python
def compare(game, guess):
    """I think we all remember that feeling when the result of some long-awaited
    event is finally known. The feelings and thoughts you have at that moment are
    definitely worth noting down and comparing.
    Your task is to determine if a person correctly guessed the results of a number of matches.
    You are given two arrays of scores and guesses of equal length, where each index shows a match.
    Return an array of the same length denoting how far off each guess was. If they have guessed correctly,
    the value is 0, and if not, the value is the absolute difference between the guess and the score.

    example:

    compare([1,2,3,4,5,1],[1,2,3,4,2,-2]) -> [0,0,0,0,3,3]
    compare([0,5,0,0,0,4],[4,1,1,0,0,-2]) -> [4,4,1,0,0,6]
    """
    return [abs(score - guess) for score, guess in zip(game, guess)]
```


To solve this problem, we need to iterate through the list of extensions and calculate the "strength" for each. The strength is defined as the count of uppercase letters minus the count of lowercase letters. We keep track of the maximum strength found so far and the corresponding extension name. Since we need to return the first occurrence in case of a tie, we only update the "strongest" variable if we find a strength strictly greater than the current maximum.

Complexity:
- Time: O(N * M) where N is the number of extensions and M is the average length of an extension string.
- Space: O(1) (excluding the input/output storage).

```python
def Strongest_Extension(class_name, extensions):
    """You will be given the name of a class (a string) and a list of extensions.

    in the extension's name, the strength is given by the fraction CAP - SM.
    You should find the strongest extension and return a string in this
    format: ClassName.StrongestExtensionName.
    If there are two or more extensions with the same strength, you should
    choose the one that comes first in the list.

    if not extensions:
        return class_name

    max_strength = float('-inf')
    strongest_ext = ""

            elif char.islower():
                sm += 1

To solve this problem, we need to check if any cyclic rotation of string `b` exists as a substring within string `a`.

A cyclic rotation of a string `b` of length `n` can be generated by concatenating `b` with itself (`b + b`) and taking any substring of length `n`. For example, if `b` is "abc", `b + b` is "abcabc", and the rotations are "abc", "bca", and "cab".

The approach is:
1. Determine the length of `b`.
2. Generate all possible rotations of `b`.
3. Check if any of these rotations exist as a substring in `a`.
4. If any rotation is found, return `True`. If none are found after checking all rotations, return `False`.

Complexity:
- Time: $O(k \cdot m)$, where $k$ is the length of $b$ and $m$ is the length of $a$ (due to substring searching).
- Space: $O(k)$ to store the rotations or the doubled string.

```python
def cycpattern_check(a, b):
    """You are given 2 words. You need to return True if the second word or any of its rotations is a substring in the first word
    cycpattern_check("abcd","abd") => False

    if not b:
        return True

    n = len(b)
    # A string concatenated with itself contains all its cyclic rotations
    # as substrings of length n.

    # We iterate through all possible rotations of b
    # A rotation starts at index i and has length n

To solve this problem, we need to iterate through each digit of the given integer. Since the input can be negative, we first take the absolute value to ensure we only process the digits. We then convert the number to a string or use modulo arithmetic to isolate each digit. For each digit, we check if it is divisible by 2 to determine if it is even or odd, incrementing the respective counters.

Complexity:
- Time Complexity: O(d), where d is the number of digits in the integer.
- Space Complexity: O(1) (excluding the string conversion if used).

```python
def even_odd_count(num):
    """Given an integer. return a tuple that has the number of even and odd digits respectively.

        if digit % 2 == 0:
            even_count += 1
        else:
            odd_count += 1

    return (even_count, odd_count)

To convert an integer to a Roman numeral, we can map the standard Roman numeral symbols (including subtractive combinations like IV, IX, XL, XC, CD, and CM) to their integer values in descending order. By iterating through this mapping, we subtract the value from the input number and append the corresponding symbol to a result string until the number reaches zero.

Complexity:
- Time: O(1) because the input range is fixed (1 to 1000).
- Space: O(1) to store the mapping and the result string.

```python
def int_to_mini_roman(number):

To determine if three sides form a right-angled triangle, we use the Pythagorean theorem ($a^2 + b^2 = c^2$), where $c$ is the longest side (hypotenuse). Since the inputs $a, b, c$ can be provided in any order, we must first identify the maximum value among them.

Complexity:
- Time Complexity: $O(1)$ as we perform a constant number of arithmetic operations.
- Space Complexity: $O(1)$.

    return sides[0]**2 + sides[1]**2 == sides[2]**2
```


To solve this problem, we need to iterate through the list of strings and determine the count of unique characters for each word. We can use a `set` to find the unique characters of a string.

To handle the tie-breaking condition (lexicographical order), we can use a custom key for the `max` function. The key will be a tuple: `(number_of_unique_characters, negative_lexicographical_order)`. However, a cleaner way is to use the `max` function with a key that returns the count of unique characters, and then handle the lexicographical order by sorting the list first or by using a custom comparison.

Actually, the most efficient way is to use `max()` with a key that returns the count of unique characters. To handle the lexicographical tie-break (where we want the *smallest* string alphabetically among those with the *maximum* count), we can sort the list lexicographically first, then find the max based on unique counts. Since `max()` returns the first occurrence of the maximum value, the lexicographically first word will be preserved.

```python
def find_max(words):
    """Write a function that accepts a list of strings.
    The list contains different words. Return the word with maximum number
    of unique characters. If multiple strings have maximum number of unique
    characters, return the one which comes first in lexicographical order.

    if not words:
        return ""

    # Sort lexicographically first to handle the tie-break condition.
    # max() returns the first occurrence of the maximum value.
    sorted_words = sorted(words)

    # Find the word with the maximum number of unique characters.
    # The key is the length of the set of characters in the word.
    result = max(sorted_words, key=lambda w: len(set(w)))

    return result

To solve this problem, we need to determine how many carrots the rabbit can actually eat based on the `need` and the `remaining` stock.

1. The rabbit wants to eat `need` carrots.
2. However, the rabbit can only eat what is available in the `remaining` stock. Therefore, the actual amount eaten is the minimum of `need` and `remaining`.
3. The total number of carrots eaten will be the initial `number` plus the amount actually eaten.
4. The remaining stock will be the initial `remaining` minus the amount actually eaten.

Complexity:
- Time Complexity: O(1) as we are performing basic arithmetic.
- Space Complexity: O(1) as we are returning a fixed-size list.

```python
def eat(number, need, remaining):
    """

To solve this problem, we need to evaluate an algebraic expression where the order of operations (PEMDAS/BODMAS) applies. Specifically, exponentiation (`**`) has the highest precedence, followed by multiplication (`*`) and floor division (`//`), and finally addition (`+`) and subtraction (`-`).

Since the expression is provided as a sequence of operands and operators, we can use a stack-based approach or a two-pass approach to handle precedence. A common way to handle this is to first process all multiplications and divisions from left to right, and then process all additions and subtractions from left to right. However, because exponentiation is right-associative in Python (e.g., `2**3**2` is `2**(3**2)`), but the problem implies a linear sequence of operations, we will treat the sequence as a standard left-to-right evaluation for operators of the same precedence, while respecting the standard hierarchy.

Actually, the standard way to evaluate such a sequence is to treat it like a mathematical string. We can convert the lists into a list of tokens and use a standard expression evaluator or a simplified two-pass approach:
1. Handle `**` (Exponentiation).
2. Handle `*` and `//` (Multiplication and Floor Division).
3. Handle `+` and `-` (Addition and Subtraction).

```python
def do_algebra(operator, operand):
    """
    Given two lists operator, and operand. The first list has basic algebra operations, and
    the second list is of integers. Use the two given lists to build the algebric
    expression and return the evaluation of this expression.

    # Combine operands and operators into a list of tokens
    # Example: [2, '+', 3, '*', 4, '-', 5]
    tokens = []

        if i < len(operator):
            tokens.append(operator[i])

    # Pass 1: Handle Exponentiation (**)
    # Note: In standard math, ** is right-associative.
    # However, in most "list of operators" problems, left-to-right is expected
    # unless specified. We will follow standard Python precedence.

    while i < len(tokens):

            if tokens[i] == '*':
                res = int(left * right)

To solve this problem, we need to check two conditions:
1. Does the string contain any alphabetic characters?
2. If it does, iterate through the string and swap the case of each letter while keeping non-letters unchanged.
3. If it contains no letters, return the reversed string.

Complexity:
- Time: O(n), where n is the length of the string, as we iterate through the string at most twice.
- Space: O(n) to store the resulting string.

```python
def solve(s):
    """You are given a string s.
    if s[i] is a letter, reverse its case from lower to upper or vise versa,
    otherwise keep it as it is.
    If the string contains no letters, reverse the string.
    The function should return the resulted string.
    Examples
    solve("1234") = "4321"
    solve("ab") = "AB"
    solve("#a@C") = "#A@c"
    """
    # Check if there is at least one letter in the string
    has_letter = any(char.isalpha() for char in s)

    if not has_letter:
        # If no letters, return the reversed string
        return s[::-1]
    else:
        # If letters exist, swap the case of each letter
        result = []
        for char in s:
            if char.isalpha():
                if char.isupper():
                    result.append(char.lower())
                else:
                    result.append(char.upper())
            else:
                result.append(char)
        return "".join(result)
```


To implement this, I will use the built-in `hashlib` library. Since `hashlib.md5()` requires a bytes-like object, I must encode the input string (defaulting to UTF-8). I will also include a check for the empty string as specified.

```python
import hashlib

def string_to_md5(text):
    """
    Given a string 'text', return its md5 hash equivalent string.
    If 'text' is an empty string, return None.

    >>> string_to_md5('Hello world') == '3e25960a79dbc69b674cd4ec67a72c62'
    """
    if text == "":
        return None

    # Encode the string to bytes before hashing
    encoded_text = text.encode('utf-8')
    # Generate the md5 hash
    md5_hash = hashlib.md5(encoded_text).hexdigest()

    return md5_hash
```


To solve this problem, we need to identify the range between `a` and `b` (regardless of which is larger), iterate through every integer in that range, and check if the integer itself is an even digit.

Wait, looking at the examples:
- `generate_integers(2, 8)` returns `[2, 4, 6, 8]`. These are even numbers.
- `generate_integers(10, 14)` returns `[]`. Even though 10, 12, and 14 are even numbers, they are not "digits" (digits are 0-9).

Therefore, the logic is:
1. Determine the minimum and maximum of `a` and `b`.
2. Iterate through the range from `min` to `max` inclusive.
3. Check if the number is a single digit (0-9) AND if it is even.
4. Return the list of such numbers in ascending order.

```python
def generate_integers(a, b):
    """
    Given two positive integers a and b, return the even digits between a
    and b, in ascending order.

    For example:
    generate_integers(2, 8) => [2, 4, 6, 8]
    generate_integers(8, 2) => [2, 4, 6, 8]
    generate_integers(10, 14) => []
    """
    start = min(a, b)
    end = max(a, b)
    result = []

    for num in range(start, end + 1):
        # A "digit" is a single-digit number (0-9)
        # The problem specifies positive integers, but we check 0-9 for safety
        if 0 <= num <= 9 and num % 2 == 0:
            result.append(num)

    return sorted(result)
```
