CF 103886P - Cereal Mountains

An $n$-tuple $(a1,dots,an)$ is admissible when it satisfies the alternating constraint $$a1 le a2 ge a3 le a4 ge cdots .$$ Let $mathcal{A}n$ denote the set of all such binary $n$-tuples.

CF 103886N - Shopping Groups

We are given a collection of intervals, where each interval represents a “shopping group candidate” occupying a range on a line. Two intervals are considered connected if their ranges overlap at least at one point.

CF 103886M - Cereal Grids II

We are given an $n times n$ grid and a number $k$. We need to place $k$ identical objects (called $w$ in the statement) onto distinct cells of the grid. The objective is to maximize a score that depends on how these chosen cells interact with their neighbors in the grid.

CF 103886L - Fossil Excavation

We are working on a grid where only a small number of cells actually matter: a base location and several fossil locations. The grid itself can be large and mostly empty, but movement is only relevant through shortest paths on the grid.

CF 103886I - Smuggling Cereal

We are given a sequence of boxes arranged in a line, where each position may contain a box with some property that affects whether it can be shifted left through the line.

CF 103886K - Terraforming

We are given a one-dimensional landscape represented by an array of heights. As a water level rises from low to high, positions become submerged once the water level strictly exceeds their height.

CF 103886H - Bombs and Balloons

We are given a rectangular grid with multiple rows and columns. Each cell in this grid either contains a balloon or a bomb. Two agents move through the grid row by row, and in each row they choose positions in that row to collect balloons.

CF 103886G - Vacation

The problem statement you provided is incomplete. It only contains the construction idea and does not include the actual input/output specification or sample tests. Because of that, I cannot produce a correct editorial or Python solution.

CF 103886F - Cereal Schemes

We are given an array of integers and a requirement to split it into exactly k contiguous subarrays. For any such partition, each subarray has an OR value computed across its elements.

CF 103886E - Jeopardized Projects

The problem asks us to compute a value for each given integer $x$, where each $x$ represents a “project size” or target sum.

CF 103886B - Cereal Robber

We are working on a geometric optimization problem on a discrete grid. Imagine a 2D classroom-like layout where some cells contain “hall monitors” and the outer boundary of the grid acts like a hard wall that also restricts movement.

CF 103886A - Cereal Sort

We are given a sequence of red pandas sitting in a line, where each panda has an integer ID. The process we care about repeatedly looks at these IDs in increasing order of value, and whenever a particular ID appears in the current line, all pandas with that ID contribute to…
