hi @tanjuljain19
Writing a simple recursive solution will time out due to exponential complexity i.e. O (3n ).
Writing a linear dynamic programming solution using arrays will exceed memory limit since N can be 109 in worst case.
To circumvent both of the a aforementioned problem, we can use maps and memoization.
