<div><p>Write an efficient algorithm that searches for a value in an <i>m</i> x <i>n</i> matrix. 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>

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

<p>Consider the following matrix:</p>

<pre>[
  [1,   4,  7, 11, 15],
  [2,   5,  8, 12, 19],
  [3,   6,  9, 16, 22],
  [10, 13, 14, 17, 24],
  [18, 21, 23, 26, 30]
]
</pre>

<p>Given&nbsp;target&nbsp;=&nbsp;<code>5</code>, return&nbsp;<code>true</code>.</p>

<p>Given&nbsp;target&nbsp;=&nbsp;<code>20</code>, return&nbsp;<code>false</code>.</p>
