Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Count the number of unique paths from (0, 0) to (7, 5) while passing through (3, 3) without retracing steps.

💡 Hint: Break down the problem into manageable segments.

Challenge 2 Hard

Create a dynamic programming model for counting paths in an 8x8 grid with two blocked intersections at (5, 4) and (6, 6).

💡 Hint: Remember the iterative filling approach we discussed!
