The input is a natural number n — the number of rows and columns in the matrix, the number of matrix elements (integers) line by line separated by a space. draw the maximum element below the main diagonal. The elements of the main diagonal are also taken into account.

def matrix(n):
  for i in range(n):
    for j in range(n):
      print(max(i, j) + 1, end=" ")
    print()
