<p><strong>No-Zero integer</strong> is a positive integer that <strong>does not contain any <code>0</code></strong> in its decimal representation.</p>

<p>Given an integer <code>n</code>, return <em>a list of two integers</em> <code>[A, B]</code> <em>where</em>:</p>

<ul>
	<li><code>A</code> and <code>B</code> are <strong>No-Zero integers</strong>.</li>
	<li><code>A + B = n</code></li>
</ul>

<p>The test cases are generated so that there is at least one valid solution. If there are many valid solutions you can return any of them.</p>

<p>&nbsp;</p>
<p><strong>Example 1:</strong></p>

<pre>
<strong>Input:</strong> n = 2
<strong>Output:</strong> [1,1]
<strong>Explanation:</strong> A = 1, B = 1. A + B = n and both A and B do not contain any 0 in their decimal representation.
</pre>

<p><strong>Example 2:</strong></p>

<pre>
<strong>Input:</strong> n = 11
<strong>Output:</strong> [2,9]
</pre>

<p>&nbsp;</p>
<p><strong>Constraints:</strong></p>

<ul>
	<li><code>2 &lt;= n &lt;= 10<sup>4</sup></code></li>
</ul>
