题目描述 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 $.) 输入格式 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). The final input line will contain a single $ 0 $ on a line by itself. 注意输入数据中，$ VeryLongInteger $ 可能有前导 $ 0 $ 输出格式 Your program should output the sum of the $ VeryLongIntegers $ given in the input. 输入样例 123456789012345678901234567890 123456789012345678901234567890 123456789012345678901234567890 0 输出样例 370370367037037036703703703670
