Given two integers, n and m, how many digits have nm?
2 and 10 - 210 = 1024 - 4 digits
3 and 9 - 39 = 19683 - 5 digits
The input is composed of several test cases. The first line has an integer C, representing the number of test cases. The following C lines contain two integers N and M (1 <= N, M <= 100).
For each input test case of your program, you must print an integer containing the number of digits of the result of the calculated power in the respective test case.
