Javas type int has a limit on how large an integer it can store. This limit can be circumvented by representing an integer as an array of digits. Write an interactive program that adds two integers of up to 50 digits each.

Here is one sample run:

first number: 810000320000004000000032004100009

second number: 310000820030004000000079004100003

sum is: 1120001140030008000000111008200012
