This puzzle seems to me a better fit for the medium category that for the easy one. Add the keyword
Memoization in the
Details under the section
What I'll learn? would be really useful as well. Thanks to the ones that pointed out the
Memoization technique. That really helped me to solve this puzzle.
Good idea indeed. Done.
Solved subject without Memoization and recursion. Solution was event-driven. Dependency chains “auto” solved after cell calculation by subscription to solved event.
Each cell calculated one time.
