🍱 Solution

class Solution {
    public int lengthOfLastWord(String s) {
        String st[]=s.split(" ");
        int l=st.length;
        if(s==null){
            return 0;
        }
        if(l<=0)
            return 0;
        
        String lastword=st[l-1];
        return lastword.length();
    }
