Matrix help

[IvanIvanov123]

This is the exercise. I tried to make it but couldn't. I'll be very glad if somebody would help me. Thank you in advance.
There's a square matrix of row n (1 <= n <= 10). Write a program in which you have to fill in the elements of the matrix and display them. Find the sum of the odd numbers
below the main diagonal, the sum of the even numbers above the secondary diagonal and derive their
collection.
