# Transpose

This simple program asks you to print the transpose of the matrix.

A transpose of a matrix A can be defined as a matrix AT where AT[i][j]=A[j][i].

So the Transpose of a matrix with dimensions M x N has dimensions N x M.

**Input**

It First gives an Integer T denoting Number of test cases.

Then Each Test case starts with two Intgeres on one line R and C,

denoting the number of rows and the number of columns respectively.

Then Follow R lines of input each containg C integers seperated by space.

**Output**

For each Test case ,

N lines of Output each containing M integers which represent the transpose of above matrix.

**constraints**

T<=50

R,C<=50
