When user enters C or c program wants from the user to enter an integer numbers
which are between 1 and 20. (1≤n≤20). Then the program prints a circular nxn matrix
as in the following form:
n n-1 n-2 3 2 1
1 n n-1 4 3 2
2 1 n 5 4 3
n-3 n-4 n-5 ... n n-1 n-2
n-2 n-3 n-4 1 n n-1
n-1 n-2 n-3 2 1 n
For example if user enters 5 then the message will be like the following:BIL-200 GROUP A,B,C HOMEWORK PROJECT 3 07/11/2012
3
5 4 3 2 1
1 5 4 3 2
2 1 5 4 3
3 2 1 5 4
4 3 2 1 5
For example if user enters 3 then the message will be like below:
3 2 1
1 3 2
2 1 3
