IntegerInquiry 

One of the first users of BIT's new supercomputer was ChipDiller. He extended his exploration of powers of 3 to go from 0 to333 and he explored taking various sums of those numbers.

``This supercomputer is great,'' remarked Chip. ``I only wishTimothy were here to see these results.'' (Chip moved to a newapartment, once one became available on the third floor of theLemon Sky apartments on Third Street.)

Input

The input will consist of at most 100 lines of text, each ofwhich contains a single VeryLongInteger. Each VeryLongInteger willbe 100 or fewer characters in length, and will only contain digits(no VeryLongInteger will be negative).

The final input line will contain a single zero on a line byitself.

Output

Your program should output the sum of the VeryLongIntegers givenin the input.
