✅ HashMap
✅ Prefix Sum
✅ Interview Favorite

The trick is simple:
Find the brick edge position that appears in the maximum number of rows. Draw the vertical line there to cross the fewest bricks.

Time Complexity: O(N)
Space Complexity: O(N)

💡 Remember:
Minimum Bricks Crossed = Total Rows − Maximum Edge Frequency
