Description:
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.
Example:
Input: "Hello World"
Output: 5
My code:
/**
* @param {string} s
* @return {number}
*/
var lengthOfLastWord = function(s) {
let arr = s.trim().split(' ');
return arr[arr.length - 1].length;
};
