Unofficial Hints
If somebody want to see the codes.
Problem E — Query Color
Problem F — Shanks Test
Problem D — The Ancient Tree
my O(n^2logn) did not pass D. what was the intended Time complexity?
It is possible to solve in $$$O(n \log(n)+q)$$$
Is it possible to upsolve the problems now? I am unable to submit it on codechef @appu_nitd.
Codechef takes some time to move the problems to practice. After that it's possible to submit and upsolve the problems. It generally takes 1 day from the day of contest. Hope you enjoy upsolving!
More than 24 hours have passed but still codechef is not letting us to do it so. Could you please provide editorial or fix this problem asap ?
Problems have moved in Practise Section you can try upsolving all the problems.
Anybody else missed word "even" in the first operation description and solved harder version of B?)
