+<h2><a href="https://leetcode.com/problems/subrectangle-queries/">1476. Subrectangle Queries</a></h2><h3>Medium</h3><hr><div><p>Implement the class <code>SubrectangleQueries</code>&nbsp;which receives a <code>rows x cols</code> rectangle as a matrix of integers in the constructor and supports two methods:</p>
+
+<p>1.<code>&nbsp;updateSubrectangle(int row1, int col1, int row2, int col2, int newValue)</code></p>
+
+<ul>
+	<li>Updates all values with <code>newValue</code> in the subrectangle whose upper left coordinate is <code>(row1,col1)</code> and bottom right coordinate is <code>(row2,col2)</code>.</li>
+</ul>
+
+<p>2.<code>&nbsp;getValue(int row, int col)</code></p>
+
+<ul>
+	<li>Returns the current value of the coordinate <code>(row,col)</code> from&nbsp;the rectangle.</li>
+</ul>
+
+<p>&nbsp;</p>
+<p><strong>Example 1:</strong></p>
+
+<pre><strong>Input</strong>
+["SubrectangleQueries","getValue","updateSubrectangle","getValue","getValue","updateSubrectangle","getValue","getValue"]
+[[[[1,2,1],[4,3,4],[3,2,1],[1,1,1]]],[0,2],[0,0,3,2,5],[0,2],[3,1],[3,0,3,2,10],[3,1],[0,2]]
+<strong>Output</strong>
+[null,1,null,5,5,null,10,5]
+<strong>Explanation</strong>
+SubrectangleQueries subrectangleQueries = new SubrectangleQueries([[1,2,1],[4,3,4],[3,2,1],[1,1,1]]);  
+// The initial rectangle (4x3) looks like:
+// 1 2 1
+// 4 3 4
+// 3 2 1
+// 1 1 1
+subrectangleQueries.getValue(0, 2); // return 1
+subrectangleQueries.updateSubrectangle(0, 0, 3, 2, 5);
+// After this update the rectangle looks like:
+// 5 5 5
+// 5 5 5
+// 5 5 5
+// 5 5 5 
+subrectangleQueries.getValue(0, 2); // return 5
+subrectangleQueries.getValue(3, 1); // return 5
+subrectangleQueries.updateSubrectangle(3, 0, 3, 2, 10);
+// After this update the rectangle looks like:
+// 5   5   5
+// 5   5   5
+// 5   5   5
+// 10  10  10 
+subrectangleQueries.getValue(3, 1); // return 10
+subrectangleQueries.getValue(0, 2); // return 5

+<strong>Output</strong>
+[null,1,null,100,100,null,20]
+<strong>Explanation</strong>
+SubrectangleQueries subrectangleQueries = new SubrectangleQueries([[1,1,1],[2,2,2],[3,3,3]]);
+subrectangleQueries.getValue(0, 0); // return 1
+subrectangleQueries.updateSubrectangle(0, 0, 2, 2, 100);
