Problem 1329
Integer Inquiry
Time Limit: 1000ms
Memory Limit: 65536kb Description
One of the first users of BIT's new supercomputer was Chip Diller. He extended his exploration of powers of 3 to go from 0 to 333 and he explored taking various sums of those numbers.
"This supercomputer is great," remarked Chip. "I only wish Timothy were here to see these results."
(Chip moved to a new apartment, once one became available on the third floor of the Lemon Sky apartments on Third Street.)
Input
The input will consist of at most 100 lines of text, each of which contains a single VeryLongInteger. Each VeryLongInteger will be 100 or fewer characters in length, and will only contain digits (no Very-LongInteger will be negative).
The final input line will contain a single zero on a line by itself
Output
your program should output the sum of the VeryLongInteger given in the input.
