I have a very simple problem for you. Given two integers A and B, your job is to multiply the product is of A × B.
Each line will contain two integers A and B. Process to end of file.Notice that the integers are very large,that means you should not process them by using 32-bit integer.You may assume the length of each integer will not exceed 1000.
For each case, output the product is of A × B in one line.
