代码(Python3) class Solution: def reverseString(self, s: List[str]) -> None: """ Do not return anything, modify s in-place instead. """ # 定义左指针 l ,初始化为 0 l: int = 0 # 定义右指针 r ,初始化为 s.length - 1 r: int = len(s) - 1 #当 l < r 时,需要继续交换...
利用string字符串数组找到中间字符,将前后字符依次交换位置,遍历输出。 C++代码: 1classSolution {2public:3stringreverseString(strings) {4inti, n;5chartemp;6n=s.size();78for(i=0; i<n/2; i++)9{10temp=s[i];11s[i] = s[n-i-1];12str[n-i-1] =temp;13}1415returns;16}17};...
方法二:双指针 C++代码: 1classSolution {2public:3voidreverseString(vector<char>&s) {4for(inti =0, j = s.size() -1; i < j; ++i,--j) {5swap(s[i], s[j]);//辅助变量实现、异或运算实现6}7}8}; python3代码: 1classSolution:2defreverseString(self, s: List[str]) ->None:3"...
