Suppose you are given the following code: class ZeroEvenOdd { public ZeroEvenOdd(int n) { ... } // constructor public void zero(printNumber) { ... } // only output 0's public void even(printNumber) { ... } // only output even numbers public void odd(printNumber) { ... } // only output odd numbers } The same instance of ZeroEvenOdd will be passed to three different threads: Thread A will call zero() which should only output 0's. Thread B will call even() which should only ouput even numbers. Thread C will call odd() which should only output odd numbers. Each of the threads is given a printNumber method to output an integer. Modify the given program to output the series 010203040506... where the length of the series must be 2n. Example 1: Input: n = 2 Output: "0102" Explanation: There are three threads being fired asynchronously. One of them calls zero(), the other calls even(), and the last one calls odd(). "0102" is the correct output. Example 2: Input: n = 5 Output: "0102030405
