Interesting and unique problem.
Was pretty hard for me to build an intuition. But solution has pattern, so I would recommend.

Had to show my CT scan to Ukrainian friend. Wanted to make it as easy as possible to see that scan so no need to install any app, etc
This is why I love about AI. 15 mins + my manual deployment: here you go, you have CT scan viewer. Just like that. Everyone can do it. Cheap and easy. Scary... and good at the same time
Btw look how big my heart is😁 I thought it is smaller.

for old school people like me who from time to time automatically open "tran" -> "translate.google.com" to recall English word:
is it only me or google translate became MASSIVELLY slower especially on first run, sometimes I'm waiting for 5 secs until I see my characters appear on the text area?

Pretty hard problem (to build intuition for). Implementation is quite easy. It is pretty unique, apart from one nice math trick you would learn here.
Otherwise no pattern I would not recommend. The math trick will be shown separately in separate post

Interesting thing that I knew about combinations - is that you can precompute them using pascal triangle.
Generally the formula is:
Pascal triangle formula is:
===
It is nice, cause I always keep forgetting combinations formula, and it is very hard for me to recreate it from the simple examples.
Now on the interview I can just state: there is formula, I don't remember but I know Pascal triangle will do the job.

Generally the formula is:
C(n, k) = n! / (k! · (n − k)!)Pascal triangle formula is:
C(n, k) = C(n−1, k−1) + C(n−1, k)===
It is nice, cause I always keep forgetting combinations formula, and it is very hard for me to recreate it from the simple examples.

Easy, 1 min codding. Thanks, leetcode, I'll have free Monday😁.
No pattern though.

A bit bullshit problem, no real pattern is here, pretty unique problem.
I would not recommend
