Given a string s consisting of some words separated by some number of spaces, return the length of the last word in the string.
A word is a maximal substring consisting of non-space characters only.

Constraints:
- 1 <= s.length <= 104
- s consists of only English letters and spaces ' '.
- There will be at least one word in s.
class Solution {
public int lengthOfLastWord(String s) {
return s.trim().length()-s.trim().lastIndexOf(" ")-1;
}
}
