Inverted L-Shaped Matrix

Given a squarematrix of size S, print the matrix in the format given in Example Input/Output section.

Input Format:
The first line contains the value size S of the matrix.
The next S lines contain S values of a given row separated by a space.

Output Format:
The S lines denote the inverted L-shaped matrix.

Boundary Condition:
1 <= S <= 100

Example Input/Output 1:
Input:
3
11 12 13
21 22 23
31 32 33

Output:
