CF 104535911.K - Drone Racing

Each participant starts at a fixed point in the plane, and we are asked to choose a single meeting point such that every participant travels the same Euclidean distance from their start to this shared destination.

CF 104535911.G - Square Sum on Segment

This crash happens before any algorithm runs, so the logic is not the issue. The failure is purely input parsing.

CF 104535911.I - GTA

We are given a number $n$, and for each test we must output two positive integers $a$ and $b$ such that their product equals $n$. The extra constraint is that neither $a$ nor $b$ is allowed to end in a zero in decimal representation.

CF 104535911.J - Multiplied Permutation

We start from a clean permutation containing the numbers from 1 to n. A segment of consecutive positions is selected, and every value inside that segment is multiplied by the same unknown integer x.

CF 104535911.H - Express Survey

We are given aggregated survey statistics from a questionnaire where each participant could tick multiple options. There are $n$ listed programming language options, plus an additional implicit option called “other”.

CF 104535911.E - Figure on the plane

We are asked to explicitly construct a convex polygon with exactly six vertices on the integer grid such that its area is exactly a given integer $S$. The only freedom we have is choosing coordinates; everything else, including convexity, ordering, and integrality, is fixed.

CF 104535911.F - City Day of Izhevsk

We are given exactly three short strings, and they are pieces of a single hidden word. The pieces are not in the correct order, but if we rearrange them properly and concatenate them, they form a known target word, “Izhevsk”.

CF 104535911.C - Alternating Generator

The current failure is no longer about parsing or unpacking. The code is now executing, but it is solving a completely different problem than the one implied by the input. Let’s focus on what the runtime behavior tells us.

CF 104535911.D - Seating Arrangement for the Exam

We are asked to construct multiple seating plans for a group of students, where each plan is a full assignment of students to desks.

CF 104535911.A - Secret Object X-0619

We are given a rectangular region of size $H times W$. The task is to cover every point inside this rectangle using a set of drones. Each drone is flexible: it can be configured to monitor any square region of any size and placed anywhere, as long as it stays within the rules.

CF 104535911.B - We Love Even Numbers

We are given a number represented as a string of digits with length $n$. The digits are all non-zero, so the number is just a clean sequence like 43153 or 654321.
