please answer this question with c++ code and cin the input not input test case
A+B problem Description Given two positive integers A and B, calculate the sum of A and B. Input The input consists of multiple test cases. The first line of the input contains an integer T ( 1 T10 ), which is the number of test cases. For each test case, it contains two integers A and B in two lines. Output For each test case, output A+B in one line. Sample Input/Output Input 2 9982443539982443531000000710000007 233333333333333666666666666666 Output 999244354708244360 899999999999999 Constraints Let A and B be the lengths of A and B.1A,B105. Hint: Both A and B can be very large. You need to find a proper way to store them and simulate the add operation
