LeetCode -- Length of last word

来源:转载

题目描述:


Given a string s consists of upper/lower-case alphabets and empty space characters ' ', return the length of last word in the string.


If the last word does not exist, return 0.


Note: A word is defined as a character sequence consists of non-space characters only.


For example,
Given s = Hello World,
return 5.


在一个字符串中,统计最后一个单词的长度。


1. 需要清空末尾字符串的空白字符
2. 直接统计


实现代码:

public class Solution { public int LengthOfLastWord(string s) { s = s.TrimEnd(); var len = 0; for(var i = s.Length - 1;i >=0; i--){ if(s[i] == ' '){ return len; } len++; } return len; }}
