Length of Last Word

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,

Java代码；

public class Solution {    public int lengthOfLastWord(String s) {        if(s.trim().equals(""))			return 0;				String[] array = s.split(" ");				return array[array.length-1].length();    }}
