Input Standard input will contain multiple test cases. The first line of the input is a single integer T which is the number of test cases. T test cases follow. The first line of each test case contains two integers n and m(1<=n,m<=100), the size of the campus. Then follow n lines, each line containing m integers. The j-th integer in the i-th line is the color of that grid, 0 stands for white color, while 1 stands for green.

Output             Results should be directed to standard output. For each case, output an integers T, the total green grids in the N*M size campus.

Sample Input 2 2 2 1 1 0 0 3 3 1 0 1 0 0 1 1 1 0

Sample Output 2 5
