CF 463C - Gargari and Bishops

We have an $n times n$ chessboard, and each cell has a non-negative integer representing money. The goal is to place exactly two bishops such that no cell is attacked by both bishops, and we maximize the total money collected from all cells that are attacked by at least one…

CF 463D - Gargari and Permutations

We are given k permutations of the numbers from 1 to n. A permutation is simply a rearrangement of these numbers. Our goal is to find the length of the longest sequence of numbers that appears in the same relative order in all k permutations.

CF 463E - Caisa and Tree

We are given a rooted tree with n nodes, each node assigned a positive integer value. Node 1 is the root. Queries ask either to find the deepest ancestor of a node v whose value shares a non-trivial greatest common divisor with v, or to update the value of a node.
