You have the four functions:

• printFizz that prints the word "Fizz" to the console,
• printBuzz that prints the word "Buzz" to the console,
• printFizzBuzz that prints the word "FizzBuzz" to the console, and
• printNumber that prints a given integer to the console.

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:

• Thread A: calls fizz() that should output the word "Fizz".
• Thread B: calls buzz() that should output the word "Buzz".
• Thread C: calls fizzbuzz() that should output the word "FizzBuzz".
• Thread D: calls number() that should only output the integers.

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

• "FizzBuzz" if i is divisible by 3 and 5,
• "Fizz" if i is divisible by 3 and not 5,
• "Buzz" if i is divisible by 5 and not 3, or
• i if i is not divisible by 3 or 5.

Implement the FizzBuzz class:

• FizzBuzz(int n) Initializes the object with the number n that represents the length of the sequence that should be printed.
• void fizz(printFizz) Calls printFizz to output "Fizz".
• void buzz(printBuzz) Calls printBuzz to output "Buzz".
• void fizzbuzz(printFizzBuzz) Calls printFizzBuzz to output "FizzBuzz".
• void number(printNumber) Calls printnumber to output the numbers.

Example 1:

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

Example 2:

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

Constraints:

• 1 <= n <= 50
