We are given a row wise sorted matrix of size r*c, we need to find the median of the matrix given. It is assumed that r*c is always odd.
The first line of input contains an integer T denoting the number of test cases. Each test case contains two integers r and c, where r is the number of rows and c is the number of columns in the array a. Next r line contains space separated c elements each in the array a.
Print an integer which is the median of the matrix.
1<= T <=100
1<= r,c <=150
1<= a[i][j] <=1000
