Higher Order Function: Write a function, whole_sum(), which takes in an integer, n. It defines and returns another function which takes in an integer, k, and returns True if the digits of k sum to n, and False otherwise.

## Higher Order Function: Whole Sum ### Task Write a function `whole_sum()` that takes in an integer `n`. It defines and returns another function, which takes in an integer `k`, and returns `True` if the digits of `k` sum to `n`, and `False` otherwise. You may use the guidelines below, or you may suggest your own solution. ### Code Snippet ```python def whole_sum(n): """ >>> whole_sum(21)(777) True >>> whole_sum(142)(10010101010) False """ def check(k): while __________: __________ __________ return __________ return __________ ``` ### Explanation The function `whole_sum()` needs to achieve the following: 1. **Parameter `n`:** An integer that represents the target sum of digits. 2. **Inner Function `check(k)`:** This function will: - Iterate through each digit of `k`. - Calculate the sum of the digits. - Return `True` if the sum equals `n`; otherwise, `False`. The example usage provided illustrates the intended behavior: - `whole_sum(21)(777)` should return `True` because the sum of the digits of 777 (7 + 7 + 7) is 21. - `whole_sum(142)(10010101010)` should return `False` because the sum of the digits of 10010101010 does not equal 142. Please fill in the blank lines to complete the inner function following the described logic.
