Quick Summary
Given a grid of horizontal and vertical bars, determine the maximum rectangular area formed after removing specified bars.
The maximum hole dimensions are independent, allowing you to calculate the largest vertical and horizontal gaps separately.
Multiply the maximum consecutive gap in rows by the maximum consecutive gap in columns to find the final area.
What This Tests
Independent dimensional analysis
Efficient gap detection without full grid simulation
Array traversal and state tracking
Complexity optimization over brute force
Common Patterns
Hashing
Sorting
Greedy
