Function Name: odd_even_diag Parameters: a 2D list (list of lists) Returns: list of lists Description: Given a 2-dimensional matrix (list of lists) with any size (n*n), modify it according to the following rules: Find the sum of the main diagonal. If the sum is an odd number, change all the values of the given matrix (except the main diagonal) to 0. If the sum is an even number, change all the values of the given matrix (except the main diagonal) to 1. Return the resulting matrix. Example 1: If argument is: [[1, 2], [4, 3]] odd_even_diag should return: [[1, 1], [1, 3]] because the sum 1 + 3 is even. Example 2: If argument is: [[1, 2, 3], [4, 5, 6], [7, 8, 9]] odd_even_diag should return: [[1, 0, 0], [0, 5, 0], [0, 0, 9]] because the sum 1 + 5 + 9 is odd.

Question
Function Name: odd_even_diag
Parameters: a 2D list (list of lists)
Returns: list of lists
Description: Given a 2-dimensional matrix (list of lists) with any size (n*n), modify it according to the following rules:
- Find the sum of the main diagonal.
- If the sum is an odd number, change all the values of the given matrix (except the main diagonal) to 0.
- If the sum is an even number, change all the values of the given matrix (except the main diagonal) to 1.
Return the resulting matrix.
Example 1:
If argument is:
[[1, 2], [4, 3]]
odd_even_diag should return:
[[1, 1], [1, 3]]
because the sum 1 + 3 is even.
Example 2:
If argument is:
[[1, 2, 3], [4, 5, 6], [7, 8, 9]]
odd_even_diag should return:
[[1, 0, 0], [0, 5, 0], [0, 0, 9]]
because the sum 1 + 5 + 9 is odd.
