58. 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.

Example:

Input: "Hello World"Output: 5
class Solution {    public int lengthOfLastWord(String s) {       return s.trim().length()-s.trim().lastIndexOf(" ")-1;    }}
