why div2 problem added on div1 and in the middle of contest. all first 3 problem removed ? is that legal ?
now they are added again don't know wtf is going on
first 5 problems are solvable in just 10 minutes.
sorry :/
It's always a must to participate in Dominater069's round.
I used this for the last problem — https://mirror.codeforces.com/blog/entry/78931.
This is the first time I have used something from this list.
There is no need for it, it can be solved with any RMQ structure like segtree. You just need to construct a directed tree from the array using the RMQ structure and then do dfs + binary search on ancestors.

even assuming you do need O(1) query, why did you need O(n) build? O(1) query normally is just sparse table
Why every problem has "101" as suffix? Any special reason for that?
shortest distance 101 div2- 103 AC
div1 — 11 AC
div4 146 AC Lmao
This actually seems like a good system to minimize the effect of cheating. They will probably get banned before ever reaching div1
This also means that someone with a very high rating is leaking the solutions. This is so disheartening because this community has given us everything for free.
