What is the number of unique paths from (0, 0) to (2, 1)?
💡 Hint: Consider the required moves to reach the end point.
True or False: Dynamic programming only calculates paths that contribute to the final answer.

Challenge Problems
Push your limits with advanced challenges
Create a function that computes the number of valid paths in a grid of size (n, m) with k blocked intersections randomly placed. Account for the overhead of blocked spaces in your calculations.
💡 Hint: Think about how you can dynamically adjust your blocked spaces as the function computes.
Propose an algorithm that not only counts paths but also lists them based on their unique sequences of moves. How would you store and display these sequences?
💡 Hint: Consider how paths can branch out and how you can track those paths towards your goal.
