一、Java

java 复制代码

class Solution {
    public void reverseString(char[] s) {
        for (int l = 0, r = s.length - 1; l < r; l++, r--) {
            s[l] ^= s[r];
            s[r] ^= s[l];
            s[l] ^= s[r];
        }
    }
}

二、C++

cpp 复制代码

#include <vector>
using namespace std;
class Solution {
public:
    void reverseString(vector<char>& s) {
        for(int l = 0, r = s.size() - 1; l < r; l++, r--) {
            s[l] ^= s[r];
            s[r] ^= s[l];
            s[l] ^= s[r];
        }
    }
};

三、Python

python 复制代码

from typing import List


class Solution:
    def reverseString(self, s: List[str]) -> None:
        l, r = 0, len(s) - 1
        while l < r:
            s[l], s[r] = s[r], s[l]
            l, r = l + 1, r - 1

四、JavaScript

javascript 复制代码

var reverseString = function (s) {
    for (let l = 0, r = s.length - 1, t; l < r; l++, r--) {
        t = s[l];
        s[l] = s[r];
        s[r] = t;
    }
}

五、Go

Go 复制代码

package main

func reverseString(s []byte) {
	l := 0
	r := len(s) - 1
	for ; l < r; {
		s[l], s[r] = s[r], s[l]
		l++
		r--
	}

}
