CF 104736L - Latam++

We are given a single string made of lowercase letters, parentheses, and arithmetic operators. Each substring of this string is interpreted as a potential expression in a very simple programming language.

CF 104736D - Deciphering WordWhiz

We are given a fixed dictionary of five-letter words, where every word uses five distinct lowercase letters. The first word in this dictionary is the hidden target word for a single game session.

CF 104736M - Meeting Point

We are given a weighted undirected graph representing a city where intersections are nodes and roads are edges with positive lengths. From a starting intersection $P$, we consider shortest-path distances as the true travel distances.

CF 104736J - Journey of the Robber

We are given a tree with $N$ cities. Each city is identified by an integer from 1 to $N$, and this numbering is also its wealth rank: larger index means richer city.

CF 104736K - Keen on Order

We are given a sequence of movie screenings over N days, where each day shows exactly one movie from a set of K distinct movies labeled from 1 to K.

CF 104736G - GPS on a Flat Earth

We are given several radio towers on a 2D integer grid. Each tower knows its exact Manhattan distance to an unknown user position, and all these distances are guaranteed to be correct simultaneously.

CF 104736I - Inversions

We are given a base string consisting of lowercase letters, and we conceptually build a much longer string by repeating this base string many times.

CF 104736H - Health in Hazard

We are working in an infinite 2D plane where the origin is fixed at the point $(0,0)$. The bear can only consider points that lie exactly at Euclidean distance $D$ from the origin, so geometrically this is a circle centered at the origin.

CF 104736A - Analyzing Contracts

We maintain a growing database of clients and answer queries about suppliers. Each supplier is fixed and described by a start day $Si$ and a cost per day $Pi$. A client arrives over time and is described by an end day $Ej$ and a revenue per day $Rj$.

CF 104736F - Forward and Backward

We are given a single integer $N$ in decimal, and we treat it as a value that can be represented in different bases. For every base $b$ in the range $[2, N]$, we write $N$ in base $b$ and check whether that representation is a palindrome when read as a digit sequence.

CF 104736E - Elevated Profits

We are given a connected network of cities forming a tree. Each city has a fixed integer label which represents its popularity value.

CF 104736C - Candy Rush

We are given a line of candies, each labeled with a brand id. We may choose a single contiguous segment of this line and buy every candy in that segment. There are exactly K family members, and each member must receive candies from exactly one brand.

CF 104736B - Blackboard Game

We are given a multiset of $3N$ integers. Two players interact with these numbers in a structured selection process that gradually assigns each number to one of three roles: red, blue, or discarded.
