<p>Write an efficient algorithm that searches for a value <code>target</code> in an <code>m x n</code> integer matrix <code>matrix</code>. This matrix has the following properties:</p>

<ul>
	<li>Integers in each row are sorted in ascending from left to right.</li>
	<li>Integers in each column are sorted in ascending from top to bottom.</li>
</ul>
