+• Reads input text file containing 2D grid from `stdin`.

+• Detects all connected components of `*` characters using Disjoint Set Union-Find (DSU).

+• Calculates bounding box coordinates during the find-union phase.
 
 • Computes the minimum bounding box for each component.
 
 • Filters for the largest non-overlapping bounding box.
 
+• Filters and compares boxes using area and coordinates.

 • Optionally returns all non-overlapping boxes in sorted order.
 
+• Returns empty string if no valid boxes found.

 • Handles malformed input with a clear "Error" output.
 
 • Efficient for large grids (10,000 × 10,000).
