Hi, From the first that i started CP i always liked problems that could be solved with some random in it, so i searched a lot but didn't find a random problemset.

now i'm making one :D

I'm adding these two. thanks

Where can i learn more about this kind of problems?

I don’t know :D

I remember two recent problems that could be solved with random.

1061F - Lost Root — This is an interactive problem, i have seen many such problems solved with random, if I will remember them, I will post here.

1198F - GCD Groups 2

Thanks, added to part two

There are some randomization problems in this blog — https://codeforces.com/blog/entry/51244

There's also this problem 862C, it has a proved solution but many solved it with a random solution like this one 30547784.

It's already in part one.
