<p>You are given an <code>m x n</code> matrix <code>M</code> initialized with all <code>0</code>'s and an array of operations <code>ops</code>, where <code>ops[i] = [a<sub>i</sub>, b<sub>i</sub>]</code> means <code>M[x][y]</code> should be incremented by one for all <code>0 <= x < a<sub>i</sub></code> and <code>0 <= y < b<sub>i</sub></code>.</p>
|
|
|
|
<p>Count and return <em>the number of maximum integers in the matrix after performing all the operations</em>.</p>

<pre>
|
|
<strong>Input:</strong> m = 3, n = 3, ops = [[2,2],[3,3]]
|
|
<strong>Output:</strong> 4
|
|
<strong>Explanation:</strong> The maximum integer in M is 2, and there are four of it in M. So return 4.
