CF 104887N - Networks Make the Net Work

We are given an undirected graph where vertices are named computers and edges are cables between them. Each test case describes one such network. Originally, each of Alice, Bob, and Cindy started with a specific fixed structure on five computers.

CF 104887J - Jolly Divisors

For every integer $n$, we are asked to look for divisors $d$ with a stronger-than-usual property: not only must $d$ divide $n$, but $d^k$ must also divide $n$. Among all such divisors, we take the largest one for each $n$.

CF 104887K - Kyuuing Theory

We are given a fixed order of students in a queue. Each student needs a fixed amount of time to complete their exam, and there are $k$ instructors who can process students in parallel.

CF 104887I - Injurious Company

We are given a starting point in the plane and a fixed sequence of moves. Each move has two pieces of information: a maximum length $Ki$ and a constraint on direction type, either horizontal or vertical.

CF 104887H - Harana

Each position in the input represents a note in a song. At position i, there is an intended note si and Bob actually sings bi. If nothing else changed, the mismatch at position i is simply the absolute difference between these two values.

CF 104887F - Five-Needle Telegraph

The structure in this problem is a rotated grid that looks like a diamond. Each position in this diamond contains a letter, except the middle horizontal line of length $n$, which contains needles instead of letters.

CF 104887C - Canonizing Cannonade

We are working on an $r times c$ grid where some cells contain soldiers. The goal is to place exactly $m$ soldiers so that a specific “destruction game” has a very precise difficulty.

CF 104887B - Balarila

We are given a single lowercase string. We are allowed to choose an ordered pair of distinct consonants, written as x followed by y. In a modified counting system, every occurrence of the adjacent substring xy is treated as one character instead of two.

CF 104887A - ABCs of Men and Women, Part 2

We are given a timeline of cooking assignments for three people, encoded as a string where each character is one of A, B, or C. Each position represents one day, and exactly one person cooks on that day.
