Answer 1

M, N = input('Enter the size of matrix M N: ').split()
M, N = int(M), int(N)
matrix = []
for x in range(M):
    matrix.append(list(map(int, input("Input the elements of the matrix: ").split())))
for x in range(M):
    for y in range(N):
        if not((x == y) or (x == N - y - 1)):
            matrix[x][y] = 0
for element in matrix:
    print(*element)
