Here are the test inputs to evaluate the performance of your code. The first line of the input file contains the dimensions of the matrix. Every row thereafter represents an element in the matrix in COO format. The output file is also in the COO format. Test input 1 : Test 1 Matrix A Test 1 Matrix B Sample Output 1: Test 1 Output Test input 2 : Test 2 Matrix A Test 2 Matrix B Sample Output 2: Test 2 Output Test input 3 : Test 3 Matrix A Test 3 Matrix B Sample Output 3: Test 3 Output
