+ "Row Wise Sum"
+ 
+For a given two-dimensional integer array/list of size (N x M), find and print the sum of each of the row elements in a single line, separated by a single space.
+Input Format :
+The first line contains an Integer 't' which denotes the number of test cases or queries to be run. Then the test cases follow.
+
+First line of each test case or query contains two integer values, 'N' and 'M', separated by a single space. They represent the 'rows' and 'columns' respectively, for the two-dimensional array/list.
+
+Second line onwards, the next 'N' lines or rows represent the ith row values.
+
+Each of the ith row constitutes 'M' column values separated by a single space.
+Output Format :
+For each test case, print the sum of every ith row elements in a single line separated by a single space.
+
+Output for every test case will be printed in a seperate line.
+Constraints :
+1 <= t <= 10^2
+0 <= N <= 10^3
+0 <= M <= 10^3
+Time Limit: 1sec
