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,
Given s = "Hello World",
return 5.
1 public class Solution { 2 public int lengthOfLastWord(String s) { 3 if(0 == s.length()) 4 return 0; 5 s = s.trim(); 6 int count = 0; 7 8 for(int i = s.length() - 1; i >= 0;i--){ 9 if(‘ ‘ == s.charAt(i)){10 break;11 }12 count++;13 }14 return count;15 }16 }
