Question for you: What is the space and time complexity of the solution in the video?

Mo Elsherif :
I don’t think you need a whole array, you can achieve this by just using two variables

For linear DP, tight space and speed bottom-up is better

Already saw parts 1 & 2 and this solution is just amazing

mfrdnzmn :
what if instead after we set up the n+1 array with all 0s, we iterate through the array sequentially and at each iteration we increment i+1 and i+2 by one?

Do you have any advice on good approaches to doing leetcode? I’m starting with blind 75 but I was wondering if I should focus on solving the problems optimally under 20 mins and then move on or cover a range of different problems even if I haven’t solved them all under 20 mins.

I get that you’re introducing this with an easy example to teach the concept, but the solution a first year CS student would come up with—iterative loop with “prev” and “prevPrev”—is more efficient and easier to understand than recursion or DP

I don’t even know when im using recursion, it just happens✨

great mini-series, your passion and skill for teaching is well displayed!! for the bonus questions: O(n) time and space complexity, and we can bring this down to O(1) by using a few variables instead of a list, right?

It makes me sad it did run

I truly have learned nothing so far in my degree if this is entry level leetcode

The Mathematic Fanatic :
In what way is this better than the memoized recursive solution shown in part 2?
