[编程题]A + B
- 热度指数：4754 时间限制：C/C++ 1秒，其他语言2秒 空间限制：C/C++ 64M，其他语言128M
- 算法知识视频讲解
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
