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
\n

 

\n

Constraints:

\n\n\n", "translatedTitle": "交替打印字符串", "translatedContent": "

编写一个可以从 1 到 n 输出代表这个数字的字符串的程序,但是:

\n\n\n\n

例如,当 n = 15,输出: 1, 2, fizz, 4, buzz, fizz, 7, 8, fizz, buzz, 11, fizz, 13, 14, fizzbuzz

\n\n

假设有这么一个类:

\n\n
\nclass FizzBuzz {\n  public FizzBuzz(int n) { ... }               // constructor\n  public void fizz(printFizz) { ... }          // only output \"fizz\"\n  public void buzz(printBuzz) { ... }          // only output \"buzz\"\n  public void fizzbuzz(printFizzBuzz) { ... }  // only output \"fizzbuzz\"\n  public void number(printNumber) { ... }      // only output the numbers\n}
\n\n

请你实现一个有四个线程的多线程版  FizzBuzz, 同一个 FizzBuzz 实例会被如下四个线程使用:

\n\n
    \n\t
  1. 线程A将调用 fizz() 来判断是否能被 3 整除,如果可以,则输出 fizz
  2. \n\t
  3. 线程B将调用 buzz() 来判断是否能被 5 整除,如果可以,则输出 buzz
  4. \n\t
  5. 线程C将调用 fizzbuzz() 来判断是否同时能被 3 和 5 整除,如果可以,则输出 fizzbuzz
  6. \n\t
  7. 线程D将调用 number() 来实现输出既不能被 3 整除也不能被 5 整除的数字。
  8. \n
\n\n
