Check String Length

Problem

Given a string s, return true if its length is a multiple of 3, and false otherwise.

Examples

isLengthMultipleOfThree("hello")
// false
// The length of the string "hello" is 5, which is not a multiple of 3.

isLengthMultipleOfThree("abc") // true
isLengthMultipleOfThree("abcdef") // true
isLengthMultipleOfThree("ab") // false
