What is the total number of paths from (0, 0) to (5, 10) with no blocks?
💡 Hint: Calculate paths based on combinations.
True or False: The number of ways to pick 5 upward moves out of 15 total moves is the same as picking 10 upward moves.
💡 Hint: Remember how combinations work.

Challenge Problems
Push your limits with advanced challenges
Imagine a grid where intersections (2, 4) and (3, 3) are blocked. From (0, 0) to (5, 5), calculate the number of valid paths considering these blockages.
💡 Hint: Break the solution into manageable sections.
You have a grid shaped like an L with blockages at odd intersections. Calculate paths from (0,0) to the endpoint at the upright angle. Use dynamic programming principles here.
💡 Hint: Focus on path dependencies as you fill in your table.
