Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

On a grid of size 10x10, if there are obstacles at positions (4, 4) and (6, 7), calculate the number of unique paths from (0, 0) to (9, 9).

💡 Hint: Break it down into smaller problems: find paths to each critical point.

Challenge 2 Hard

Explain a real-world situation where the inclusion-exclusion principle might apply outside of grid paths.

💡 Hint: Think about overlapping memberships or characteristics.
