Implement the function according to the docstring.

Given three side lengths in the increasing order of length as a, b, and c, where a <= b <= c, check if the given sides are the sides of a right triangle whose perpendicular sides are of even length.

Hint: in a right triangle the square of hypotenuse is the sum of square of the other two sides.

Arguments:

• a: int - the first side length
• b: int - the second side length
• c: int - the hypotenuse length

Return:

• bool - True if the sides form a right triangle and the perpendicular sides are even, else False

Your task

Implement this function:

def is_right_triangle_with_even_sides(a: int, b: int, c: int) -> bool:

Write the function only — the arguments are read for you and the return value is printed automatically.

Arguments arrive as one Python literal per line, in this order: a, b, c.

Implement the function according to the docstring. Given three side lengths in the increasing order of length as `a`, `b`, and `c`, where `a <= b <= c`, check if the given sides are the sides of a right triangle whose perpendicular sides are of even length. *Hint: in a right triangle the square of hypotenuse is the sum of square of the other two sides.* **Arguments:** - `a: int` - the first side length - `b: int` - the second side length - `c: int` - the hypotenuse length **Return:** - `bool` - `True` if the sides form a right triangle and the perpendicular sides are even, else `False` ## Your task Implement this function: ```python def is_right_triangle_with_even_sides(a: int, b: int, c: int) -> bool: ``` Write the function only — the arguments are read for you and the return value is printed automatically. **Arguments** arrive as one Python literal per line, in this order: `a`, `b`, `c`. ## Example **Input** ``` 6 8 10 ``` **Output** ``` True ``` Implement the function according to the docstring. Given a string, check if all the odd indices are alphabets and the even indices are digits. *Note: indices start from 0.* **Arguments:** - `string: str` - the input string **Return:** - `bool` - `True` if all odd indices are alphabets and even indices are digits, else `False` ## Your task Implement this function: ```python def is_odd_indices_alpha_and_even_indices_digits(string: str) -> bool: ``` Write the function only — the arguments are read for you and the return value is printed automatically. **Arguments** arrive as one Python literal per line, in this order: `string`. ## Example **Input** ``` '1a2b3c' ``` **Output** ``` True ``` Implement the function according to the docstring. Given a list of integers, swap the values at the even indices and the odd indices by modifying the same list. **Arguments:** - `l: list` - the input list of integers **Return:** - `None` - the input list is modified inside the function. ## Your task Implement this function: ```python def swap_even_and_odd_indices(l: list) -> None: ``` Write the function only — the arguments are read for you and the return value is printed automatically. **Arguments** arrive as one Python literal per line, in this order: `l`. ## Example **Input** ``` [1, 2, 3, 4] ``` **Output** ``` [2, 1, 4, 3] ```
