推荐答案
你不能对字符串使用数学运算（parseInt（n％10））。首先需要将整个输入字符串转换为整数，然后执行相反的操作。或者，您可以将字符串拆分为一个字符数组，然后将其反转。
You cannot use mathematical operations on strings (parseInt(n%10)). You first need to convert the entire input string into an integer and then do the reverse operation. Alternatively you could just split the string into an array of characters and then reverse them.
