注意不能用正则表达式. 使用的知识点只能是js的语法范围.
先谢过了
例如:
Input: “We have 30 apples will be handed out to 10 students who need it, containing 5 foreigners ”. Output: 30 + 10 + 5 = 45
把字符串挨着扫描一遍不就完了……
typeof arr[i] === number
var str = We have 30 apples will be handed out to 10 students who need it, containing 5 foreigners;
最多设置5个标签!

付费偷看金额在0.1-10元之间
