Python: Utilize slicing ([::-1]) to quickly reverse the string. Java: Convert the string to a StringBuilder, call reverse(), and convert back to a string. C++: Employ built-in functions like std::reverse or man
1 Python 解法一:reverse 函数 ## LeetCode 344E - Reversing String, 简单做法 reverse from typing import List class Solution: def reverseString(self, s: List[str]) -> None: """ 不返回任何结果,直接修改目标字符串 """ s.reverse() 翻转除了 reverse 可以实现,[::-1]也是可以的。 不过这么写...
publicString reverseStr(String s,intk) { if(s ==null|| s.isEmpty()){returns;} StringBuilder sb =newStringBuilder(); booleanreverse =true; for(inti =0; i < s.length(); i = i + k, reverse = !reverse){ intend = (i + k) < s.length() ? (i + k -1) : s.length()-1;...

leetcode344——Reverse String(C++) Write a function that takes a string as input and returns the string reversed. Example: Given s = "hello", return "olleh". 个人博客:http://www.cnblogs.com/wdfwolf3/。 这道题就是简单的字符串逆置,在C++中字符串类型可以作为数组方式处理,所以经典的数组逆置...
建议和leetcode 344. Reverse String 反转字符串 一起学习 代码如下: #include <iostream> #include <vector> #include <map> #include <set> #include <queue> #include <stack> #include <string> #include <climits> #include <algorithm> #include <sstream> ...
1、题目: Write a function that takes a string as input and returns the string reversed. Example: Given s = "hello", return "olleh". 2、代码实现: 代码实现1: public static String reverseString(String s) { if (s == null) { return null; ...
思路很简单,从左到右依次替换就行: class Solution { public: void reverseString(vector<char>& s) { int left = 0; int right = (int)s.size() - 1; if (ri...
