Traverse Square Matrix - Spiral Clockwise

 Coding Problem Keys 

 Traverse Square Matrix - Spiral Clockwise 

 Problem Statement 

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

 Boundary Condition(s) 

2 <= N <= 100

0 <= C(i, j) <= 9999

 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.

 Solution 

 Programming Language: Python 3 Language 

n=int(input())
l=[input().split() for i in range(n)]
m=0;i=0;j=0
while(n!=n//2):
    while(j<n):
        print(l[i][j],end=" ")
        j+=1
    i+=1;j-=1
    while(i<n):
        print(l[i][j],end=" ")
        i+=1
    i-=1
    while(j>m):
        j-=1
        print(l[i][j],end=" ")
    m+=1
    while(i>m):
        i-=1
        print(l[i][j],end=" ")
    n-=1;j+=1
