I kept staring at this question in a coding interview I had today and could not come up with a solution, not even a computationally bad one. But sir, the way you explained this solution in your video is just amazing! Liked and subscribed!

This is the best explanation I've seen of this after watching three other popular youtube explanations. Thank you!

The only video that explained the correct reason behind dp[i]=dp[i-1]+dp[i-2]

I was stuck for so long, and the way you broke down the ways into two parts was my epiphany. I've watched many other videos and this is the best explanation. Such a relieve to finally understand it!

If count=0 everytime the loop starts, then why are we adding count1 or count2 to it?? Can't we just make it equal??

Why did we assign count2 value to count1 and count2 value as count at the end?

Bro your channel is really coming along. I like your thought process.

In 1, 4, 3, 2 why haven't you considered the following combinations:
4, 13, 2
4, 21, 3
4, 12, 3
24, 13

Why are we adding a digit like that? Say at 8:44 you added a 3, before that you added a 0. what are we trying to achieve by doing that? Is it just to check how last digit can be combined? or something else?
