leetcode 151. Reverse Words in a String Given an input string, reverse the string word by word. For example, Given s = "the sky is blue", return "blue is sky the". Update (2015-02-12): For C programmers: Try to solve it ......
Given an input string,reverse the string word by word.For example,Given s="the sky is blue",return"blue is sky the". 比较基础的一个题,拿到这个题,我的第一想法是利用vector来存每一个子串,然后在输出,这是一个比较简单的思路,此外,还有第二个思路,就是对所有的字符反转,然后在针对每一个子串反转...
I'm a beginner in c++ and my new teacher has given me a project on strrev. I am supposed to write a code with : char *strrev(char *s), which reverses the string order but the last character "0" should stay still. Function returns line s. Say, "Hello1234567890" shoould return "...

You need to reduce multiple spaces between two words to a single space in the reversed string. Follow up: For C programmers, try to solve itin-placeinO(1) space. 先把整个数组reverse一下再逐个reverse单词。 具体采用two pointer 和 swap 的方法来reverse。
The string consists of lower English letters only. Length of the given string and k will in the range [1, 10000] 2、代码实现 public class Solution { public String reverse(String s) { if (s == null || s.length() == 0) {
If all you're doing is reversing one string, then exiting, that's of little consequence--but if you try to use this in real code, leaking memory like this is generally unacceptable. const correctness Since you're not modifying the input string, you might as well use const in the functio...

Yes. However, your reversed string should not contain leading or trailing spaces. How about multiple spaces between two words? Reduce them to a single space in the reversed string. SOLUTION 1: 1. 先处理原字符串: 使用strim把前后的空格去除。
