//////////////////////////////////////////////Length of Last Word/////////////////////////////////////////////////////
// Given a string s consisting of some words separated by some number of spaces, return the length of the last word in the string.
// A word is a maximal substring consisting of non-space characters only.
// Example 1:
//
// Input: s = "Hello World"
// Output: 5
// Explanation: The last word is "World" with length 5.
// Example 2:
//
// Input: s = "   fly me   to   the moon  "
// Output: 4
// Explanation: The last word is "moon" with length 4.
// Example 3:
//
// Input: s = "luffy is still joyboy"
// Output: 6
// Explanation: The last word is "joyboy" with length 6.
// Constraints:
// 1 <= s.length <= 104
// s consists of only English letters and spaces ' '.
// There will be at least one word in s.
const lengthOfLastWord = function(s) {
    let str =  s.split(' ').filter((el) => el != '');
    return str[str.length - 1].length;
};

// console.log(lengthOfLastWord("Hello World"));
// console.log(lengthOfLastWord("   fly me   to   the moon  "));
// console.log(lengthOfLastWord("luffy is still joyboy"));
