Runtime error while solving the question

#1

I have solved it using recursion and I think I did write the recursive function correct ye t I am getting run time error why??

#2

ur recursive code is correct, u need to use dynamic programming to optimise it furthur and to pass all test case

#3

So should I jump to dp after solving the max question in recurssion then solving the tilling question??

#4

yeah do as many questions as you can, and come back after solving dp
