Matrix Traverse Clockwise - c

A square matrix of size N*N is provided. The program must traverse the matrix spirally and print the elements in a single line.

Input Format:
The first line contains N.Next N lines, contain N column values C(i,j) each separated by a space.

Output Format:
The first line contains N*N values separated by a space.

Boundary Conditions:
2 <= N <= 1000 <= C(i,j) <= 9999

Example Input/Output 1:
Input:
2
1 2
3 4
Output:
1 2 4 3

Example Input/Output 2:
Input:
4
1 2 3 4
5 6 7 8
9 10 11 12
13 14 15 16
Output:
1 2 3 4 8 12 16 15 14 13 9 5 6 7 11 10

Example Input/Output 3:
Input:
5
2 7 7 7 9
10 2 4 2 10
2 9 4 9 2
7 15 10 14 10
12 9 15 12 2
Output:
2 7 7 7 9 10 2 10 2 12 15 9 12 7 2 10 2 4 2 9 14 10 15 9 4
