Today I learned the new topic of String:
find the length of last word in a string;
program :
class Solution {
public int lengthOfLastWord(String s) {
int last = s.length() - 1;
while (last >= 0 && s.charAt(last) == ' ') {//to remove he spaces last--; } int start = last; while (start >= 0 && s.charAt(start) != ' ') { start--; } return last - start; }public static void main(String... args){ String a="fly of moon "; int S=lengthOfLastWlrd(a); System.out.println(S);}}
}
