Diamond Diagonal Pattern

The program must accept an integer N and a character CH as the input. The program must print the desired pattern as shown in the Example Input/Output section.

Boundary Condition(s):
4 <= N <= 50

Input Format:
The first line contains N and CH separated by a space.

Output Format:
The lines contain the desired pattern as shown in the Example Input/Output section.
