public class ZeroEvenOdd extends Object
1116 - Print Zero Even Odd.<p>Medium</p> <p>You have a function <code>printNumber</code> that can be called with an integer parameter and prints it to the console.</p> <ul> <li>For example, calling <code>printNumber(7)</code> prints <code>7</code> to the console.</li> </ul> <p>You are given an instance of the class <code>ZeroEvenOdd</code> that has three functions: <code>zero</code>, <code>even</code>, and <code>odd</code>. The same instance of <code>ZeroEvenOdd</code> will be passed to three different threads:</p> <ul> <li><strong>Thread A:</strong> calls <code>zero()</code> that should only output <code>0</code>&rsquo;s.</li> <li><strong>Thread B:</strong> calls <code>even()</code> that should only output even numbers.</li> <li><strong>Thread C:</strong> calls <code>odd()</code> that should only output odd numbers.</li> </ul> <p>Modify the given class to output the series <code>&quot;010203040506...&quot;</code> where the length of the series must be <code>2n</code>.</p> <p>Implement the <code>ZeroEvenOdd</code> class:</p> <ul> <li><code>ZeroEvenOdd(int n)</code> Initializes the object with the number <code>n</code> that represents the numbers that should be printed.</li> <li><code>void zero(printNumber)</code> Calls <code>printNumber</code> to output one zero.</li> <li><code>void even(printNumber)</code> Calls <code>printNumber</code> to output one even number.</li> <li><code>void odd(printNumber)</code> Calls <code>printNumber</code> to output one odd number.</li> </ul> <p><strong>Example 1:</strong></p> <p><strong>Input:</strong> n = 2</p> <p><strong>Output:</strong> &ldquo;0102&rdquo;</p> <p><strong>Explanation:</strong> There are three threads being fired asynchronously. One of them calls zero(), the other calls even(), and the last one calls odd(). &ldquo;0102&rdquo; is the correct output.</p> <p><strong>Example 2:</strong></p> <p><strong>Input:</strong> n = 5</p> <p><strong>Output:</strong> &ldquo;0102030405&rdquo;</p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= n <= 1000</code></li> </ul>
