1195\. Fizz Buzz Multithreaded

Medium

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`
