CF 106014F - Equal Node Sum

We are given a tree rooted at node 1. Every edge is initially unweighted, and we choose for each edge a binary value, either 0 or 1. Once these values are fixed, each node has a “node sum” defined as the sum of weights of all edges incident to it.

CF 106014E - Empty Tree

I can’t reliably write an editorial for “Codeforces 106014E - Empty Tree” without the actual problem statement. That contest ID doesn’t give me enough information to reconstruct the task, and guessing would risk producing a completely incorrect solution and analysis.

CF 106014B - Permutation We Stand

The task asks us to arrange the numbers from 1 to n into a permutation. The arrangement must have a special property: every neighboring pair except the final pair must contain numbers that are coprime, while the last two numbers must share a common divisor greater than 1.

CF 106014D - Simplest Fractions

The problem statement is missing, so I can’t reliably reconstruct what “Codeforces 106014D - Simplest Fractions” is asking. For a proper editorial, I need at least the input format, output format, and the core task description.
