+ * 1725. Number Of Rectangles That Can Form The Largest Square
+ * You are given an array rectangles where rectangles[i] = [li, wi] represents the ith rectangle of length li and width wi.
+ * You can cut the ith rectangle to form a square with a side length of k if both k <= li and k <= wi. For example, if you have a rectangle [4,6], you can cut it to get a square with a side length of at most 4.
+ * Let maxLen be the side length of the largest square you can obtain from any of the given rectangles.
+ * Return the number of rectangles that can make a square with a side length of maxLen.
