X Pattern

Given an odd integer N, print an "X" pattern of size N x N where stars appear only on the main diagonal (i == j) and the anti-diagonal (i + j == N + 1).

Input Format

A single odd integer N.

Output Format

Print N rows forming an X pattern.

Constraints:1 <= N <= 21, N is odd

Concepts Required:

Main diagonal i == jAnti diagonal i + j == N + 1Coordinate plane geometry
