title: How to create a 2D Array countdown with different line length?
body: <p>I have a little problem to understand the following task.
  I should create a 2D Array like this:</p>
  
  <pre><code>n = 4
  </code></pre>
  
  <p>--> </p>
  
  <pre><code>[4,4,4,4]
  
  [3,3,3]
  
  [2,2]
  
  [1]
  </code></pre>
  
  <p>I need only a hint how to create this 2D Array with different line length, so that i can return it in the method:</p>
  
  <pre><code>static int[][] arrayCountDown(int n) {...}
  </code></pre>
