CF 106202F - Убежища

We are given a set of points on a line representing people. Each person sits at a fixed coordinate, and we are allowed to place a certain number of shelters on the same line.

CF 106202B - Торговцы

We are given a line of merchants, each holding a single item with a price. The price of the i-th merchant is an integer in the range from 0 to $2^k - 1$, and every price is conceptually stored as a fixed-length k-bit binary number. The system processes three types of operations.

CF 106202H - Головоломка отрезков

Each item in this problem is a key that has a rigid base length and a single protruding segment somewhere along that base. When a key is placed, its base contributes to a growing horizontal line, because all chosen keys are concatenated in some order without gaps.

CF 106202D - Скелеты, кости, кладбище, черепа

We are given a graph whose vertices are points on a plane, but the geometry only matters through the x-coordinates. Each edge connects two vertices, and an edge can be thought of as a straight segment, although crossings between segments do not allow traversal.

CF 106202J - Шёлковая лестница

We are given a geometric structure built from $n$ “layers”. For each integer $i$, there is a special point at $(i,i)$. From every such point, two straight segments extend: one goes vertically down to $(i,0)$, and the other goes horizontally left to $(0,i)$.

CF 106202I - Коллекция ягод

We are given an array of fixed multipliers of length n, where each position corresponds to a bit position in a binary number of up to n bits.

CF 106202G - Песнь Нити

We are given a set of points on the plane representing insects. Exactly one of them must be chosen as the initial “source” that emits a signal at time zero.

CF 106202E - Путешествие по дереву

We are given a collection of vertex pairs on an unknown tree with n vertices. Each pair represents a travel from one vertex to another, meaning it corresponds to the unique simple path between those two vertices once a tree is fixed.

CF 106202C - Битвы с боссами

We are given a character with $n$ attributes and a list of $m$ bosses, each also described by the same $n$ attributes. Over time, the character’s attributes change via updates, and a sequence of events describes battles against bosses.
