Find the Largest Area of Square Inside Two Rectangles | LeetCode 3047 | Medium | Optimal Approach

In this video, we solve LeetCode 3047: Find the Largest Area of Square Inside Two Rectangles.

We are given multiple axis-aligned rectangles defined by their bottom-left and top-right coordinates.
Our goal is to find the maximum possible area of a square that can fit inside the intersection of at
least two rectangles. If no such square exists, return 0.

Approach:
Iterate over all pairs of rectangles.
For each pair, compute their intersection region.
If the intersection is valid, calculate its width and height.
The maximum square side possible is min(width, height).
Compute area = side × side and keep track of the maximum.

This approach works because a square can only fit inside the overlapping region of two rectangles,
and its size is limited by the smaller dimension of that overlap.

Time Complexity:
O(n²)

Space Complexity:
O(1)
