How did you do today?

[@sourabhkhandelwal689]

Very fun problem

I think the part 2 dupe solution working is a convenient consequence of how they generated your test case. They probably picked a random large number (your answer), some starting christmas grid (with no duplicates), and random velocities. From there, they simulate it (your answer number of times) going in the opposite directions of the velocities and give you those starting positions in your test case. The size of grid and number of robots make it so that the probability of there being duplicates in one cell is high, so by luck, only the initial configuration doesn't have duplicates.

I can buy this!

Hahaha Girl on the bed -Larry, are we gonna have fun? Larry looking for tree -I have a fun

Drunk Larry is Fun

While searching I determined the maximum size of a cluster of adjacent robots. I stopped my search when there more than 25 robot positions neighboring each other. This led me to the X-mas tree 🙂.

[@Algorithmist]

a lot of fun solutions to part 2!

[@ИванЗадорожный-ъ7ы]

Ok, i've finished to watch. I solved second part counting square of each area of connected robots after each second and output to file only when there is he area more than 100.

This is how I do these problems, sober.

[@ИванЗадорожный-ъ7ы]

🤣

[@ParthPatel-om4on]

why not just do this tomorrow 🤣

[@Algorithmist]

haha, clearly from the video I was not 100% decision making
