Re: big sum problem

According to the problem's statement, the input value will be at most 100 digits long. The biggest data type we have is long long, but long long can only store 2^63-1 which is 18 digits. To be able to store this you must use a string, or char array. Then you reverse them then sum each digit. Or you can use Java BigInteger :). Good luck!
