Integer Inquiry

<p> One of the first users of BIT's new supercomputer was Chip Diller.<br /> &nbsp;&nbsp;&nbsp; He extended his exploration of powers of 3 to go from 0 to 333 and he explored taking various sums of those numbers. <br /> &nbsp;&nbsp;&nbsp; "This supercomputer is great,'' remarked Chip. <br /> &nbsp;&nbsp;&nbsp; "I only wish Timothy were here to see these results.''<br /> &nbsp;&nbsp;&nbsp; (Chip moved to a new apartment, once one became available on the third floor of the Lemon Sky apartments on Third Street.) </p>

<p> 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 VeryLongInteger will be negative). </p> <p> &nbsp;&nbsp;&nbsp; The final input line will contain a single zero on a line by itself. </p>

<p> Your program should output the sum of the VeryLongIntegers given in the input. </p>
