Length of last Word

Problem Statement

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.

Given s = "Prathap Kudupu",
return 6.


  • The result  is the difference between the length of the string and and index of  empty space
     public static int optimum(String s)
  return s.trim().length()-s.trim().indexOf(' ')-1;
