MY HEX AND WHY? Unlike the decimal system (base 10) with its 10 digits, the hexadecimal system (base 16) with its 16 digits (0, 1, 2,3, 4, 5, 6,7, 8, 9, A, B, C, D, E, F) allows for more compact representation of numbers. One of the many things that can be done with hexadecimal numbers is adding them. AA+ FF 1A9 When adding the multi digit hexadecimal numbers, it seems that the number of carry operations is closely linked to the complexity of performing the task. The first two examples above seem easier than the last one since the last example required two carry-operations. Your task is to measure the number of carry-operations in adding two hexadecimal numbers Input Each line contains the pair of hexadecimal numbers. The hexadecimal numbers will be positive, and will have at most 256 digits Output Each line will consist of a number indicating the number of carry-operation for the corresponding addition questions. Sample Input: 8 3 59 A7 4FE 201 Sample Output: 0 ac
