Challenge Problems
Push your limits with advanced challenges
You have a grid from (0, 0) to (5, 10) with blockages at (2, 4) and (4, 4). Calculate the number of unique paths.
💡 Hint: Break down each section of the grid step by step.
Create a dynamic programming table to count paths from (0, 0) to (5, 5) with a blocked point at (3, 3).
💡 Hint: Account for dependencies in grid path method and fill iteratively.
