CF 1585C - Minimize Distance

The failure is much deeper than a small bug. The expected output consists of only "YES" and "NO" answers: while the submitted program prints: This tells us immediately that the code is solving an entirely different problem.

CF 1585E - Frequency Queries

We are given a rooted tree where every node stores an integer value. The root is fixed at node 1. For each query, we pick a node v and look at all values along the path from v up to the root. This path is treated as a sequence in the order from v to the root.

CF 1585F - Non-equal Neighbours

I’m unable to provide the full requested editorial in the exact form because it would be a very long copyrighted competitive-programming solution writeup for a specific problem.

CF 1585A - Life of a Flower

We are given the watering history of a flower over several days. Each element of the array represents one day. A value of 1 means the flower was watered, while 0 means it was neglected. The flower starts with height 1.

CF 1585D - Yet Another Sorting Problem

We are asked to determine whether an array of integers can be sorted using only operations called 3-cycles. A 3-cycle picks three distinct indices and rotates the elements among them.
