/*
Given number n. Print number from 1 to n. but when number is divided by 3, print fizz; when number is divided by 5, print buzz; when number is divided by both 3 and 5, print fizz buzz.
Example
If n=15, you should return ["1", "2", "fizz", "4", "buzz", "fizz", "7", "8", "fizz", "buzz", "11", "fizz", "13", "14", "fizz buzz"]
