How long did it take you to find the stair?

I am really curious about what editor key binding do you use? Is Emacs? The reason why I'm asking is because I'm using Vim right now, and it seems a little different from yours. I like the pace you code, so I really want to know, or maybe there are some shortcuts you can share?

Hey Larry, do you remember me? I am "only coding" I hope you could recall. I still watch youru videos sometimes.

@@timlu4734 not really, I only use the standard up down left right, copy paste, end of line, beginning of line, that's all!

Came to your video just reconfirm the time and space complexity of the DP solution. Happy that I was able to do all 4 this time and that too in approx. 45 mins. The other solution didn''t actually come to my mind during the context of "stars and bars". But yeah another way to approach a problem and something to learn from you. Thanks for the video.

Thanks for the explanation of the most optimized solution via combinatory. For those who have been stretching head on why k-=1, that is because you start at floor 1.
