FizzBuzz HackerRank Challenge

Solve the fizzbuzz hackerrank challenge question:

Given a number n, for each integer i in the range from 1 to n inclusive, print out one value per line as follows:

if i is a multiple of both 3 and 5, print FizzBuzz
if i is a multiple of 3(but not 5), print Fizz
if i is a multiple of 5(but not 3), print Buzz
if i is not a multiple of 3 or 5, print the value of i
