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

Note: A word is defined as a character sequence consists of non-space characters only.
For example,
Given s = "Hello World",

中文:给定一个字符串,包含大写/小写字母和空格字符,返回字符串中最后一个单词的长度。
如果最后一个单词不存在,返回0.
注意:一个单词被定义为仅包含非空字符的字符序列。
例如:
给定 s="Hello World",
返回 5.
此题可能是leetcode上面的最简单的一道题了。
Java:
public int lengthOfLastWord(String s) {
if(s.trim().equals(""))
return 0;
String[] str = s.split("\\s+");
int len = str.length;
return str[len-1].length();
