You have the four functions:

\n\n\n\n

You are given an instance of the class FizzBuzz that has four functions: fizz, buzz, fizzbuzz and number. The same instance of FizzBuzz will be passed to four different threads:

\n\n\n\n

Modify the given class to output the series [1, 2, "Fizz", 4, "Buzz", ...] where the ith token (1-indexed) of the series is:

\n\n\n\n

Implement the FizzBuzz class:

\n\n\n\n

 

\n

Example 1:

\n
Input: n = 15\nOutput: [1,2,\"fizz\",4,\"buzz\",\"fizz\",7,8,\"fizz\",\"buzz\",11,\"fizz\",13,14,\"fizzbuzz\"]\n

Example 2:

\n
Input: n = 5\nOutput: [1,2,\"fizz\",4,\"buzz\"]\n
