This one I remembered in critical moment, drum roll, from MIT lecture I watched in YouTube 5 years ago!!!

The algo:

You have current_node and neighbour. Every time you find better path to neighbour (from current_node) you update prev[neighbour] = curr.

Matrix, as always - bullshit. do not recommend, no pattern. However basic bruteforce works here, so not that hard.

It was interesting problem, as I like geometry. I have heard this sort of question was asked during one of the interviews in big tech. It is bullshit, no pattern, but nice brain puzzle, not very hard.

I bet with friend at Snow I can do 50 push up.

First he bet 20 eur for slow ones. I said no, I cant do these, I am doing explosive and fast only, but complete ones.

He said 10 eur. I said I am not that cheap bitch.
So we agreed on 16.5 eur.

Now, the q: did I make it? Do I look like a guy who can do 50 push ups?

Exactly

For the future, my 50 pushups worth 16.5 eur

The one who put shit smile - okay, I can accept this. 50 is not something to be proud of.

The one who put a clown smile - leave this channel😁😁😁

All of the people here should already know that I am clown, there is no need to state such obvious things

Folks, I need one more advice.
I am about to change avatar today hahahah, eventually.

But I got a thought, maybe the one with leetcode cap can be good candidate for avatar everywhere? Yes - face is not visible (which is plus😁). But that way it can hook potential people, wdyt?

Again let’s do poll, sorry for that.
