Stuck On CSES Problem Counting Paths: Please Provide Any Hint

Правка en1, от Gagandeep98, 2020-06-06 15:56:48

I am stuck on Counting Path 1136 problem, and unable to think how to write an approach optimal to given constraints. Any hint or help is highly appreciated.

I cannot find any place where there is any hint for CSES problems(Except DP and Range Queries).
