<p>You are given a 2D matrix <code>grid</code> of size <code>m x n</code>. You need to check if each cell <code>grid[i][j]</code> is:</p>

<ul>
	<li>Equal to the cell below it, i.e. <code>grid[i][j] == grid[i + 1][j]</code> (if it exists).</li>
	<li>Different from the cell to its right, i.e. <code>grid[i][j] != grid[i][j + 1]</code> (if it exists).</li>
</ul>

<p>Return <code>true</code> if <strong>all</strong> the cells satisfy these conditions, otherwise, return <code>false</code>.</p>
