You don't need to convert it. You can use simple memory optimisation in this question because the current state i depends only on the previous state i-1.
So you can use i%2 instead of i and that would save a lot of memory.
Have a look in this code here: Code
The thing is, I always solve dp problems recursively, so i was wondering will it be possible to solve it in a recursive fashion without exceeding the memory limit? I do understand the bottom up approach though.
