Solution: Cherry Pickup

Explore a dynamic programming approach to solve the Cherry Pickup problem by synchronizing two traversals from the top-left to the bottom-right of a grid. Understand how to maximize cherry collection by avoiding thorns and revisiting cells, using a 3D memoization table to optimize overlapping states and reduce computation.

Statement

You are given an n×nn \times n grid representing a field of cherries. Each cell in the grid can have one of three possible values:

  • 00: An empty cell that can be walked through

  • 11: A cell containing a cherry that can be picked and then passed through

  • ...
