英文A+B

A+B

题目描述

读入两个小于100的正整数A和B,计算A+B. 需要注意的是:A和B的每一位数字由对应的英文单词给出.

输入描述:

测试输入包含若干测试用例,每个测试用例占一行,格式为"A + B =",相邻两字符串有一个空格间隔.当A和B同时为0时输入结束,相应的结果不要输出.

输出描述:

对每个测试用例输出1行,即A+B的值.

示例1

输入

one + two =
three four + five six =
zero seven + eight nine =
zero + zero =

输出

3
90
96

解题思路：用map来存储数值方便操作，讨论四种情况即可。
