/**
*  This function takes in an integer numberOfTurns as an input and prints out the numbers from 1 to numberOfTurns with the following modification:
*  - If the number is divisible by 3, it prints "Fizz" instead of the number
*  - If the number is divisible by 5, it prints "Buzz" instead of the number
*  - If the number is divisible by both 3 and 5, it prints "Fizz Buzz" instead of the number
*  - If the numberOfTurns is less than 1, it will print "Number of turns must be >= 1"
*
*  - parameter numberOfTurns: the number of turns for the fizzbuzz game
