CF 105230K - Treasures

We are given a rectangular grid where each cell represents either a wall, an empty passage, a trap, the starting position, or a cell containing a numeric amount of treasure. From the starting cell, movement is allowed in four directions.

CF 105230J - Super Bishop

We are given a rectangular grid with $n$ rows and $m$ columns. A piece starts at the top-left cell and moves like a bishop, meaning it always travels diagonally.

CF 105230I - Pizzas

We are given a set of ingredients, and some pairs of ingredients are known to taste the same. That relation is not just pairwise, it extends transitively, so if ingredient A matches B and B matches C, then A, B, and C all belong to the same flavor group.

CF 105230H - Mountains

We are given a one-dimensional path encoded as a string of + and -. We start at an implicit height of zero before processing the string. Each character moves the current height by exactly one unit: + increases height by one, - decreases it by one.

CF 105230E - Great Product

We are given a single integer $n$, and we want to express it as a product of integers greater than 1. The twist is that among all possible factorizations, we are not optimizing for simplicity or minimal number of terms, but for the opposite: we want to maximize how many…

CF 105230D - Divisor Sequence

We are given a list of integers, and for each one we repeatedly apply a transformation: replace the number with the sum of its proper divisors, meaning all divisors strictly smaller than the number itself.

CF 105230B - Card Game

Each of the 60 cards corresponds to a fixed pattern over the positive integers. A number appears on a card exactly when it satisfies a certain binary condition derived from that card’s index.
