// 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.

/**
 * @param {string} s
 * @return {number}
