CF 105062F - Apple

We are given a positive integer $n$, and we treat the numbers from $1$ to $n$ as labels of items. The task is to form as many disjoint pairs as possible, where a pair $(a, b)$ is valid only if $a neq b$ and the greatest common divisor of $a$ and $b$ is greater than 1.

CF 105062C - The Other Half

Each test case gives two large integers, but the formatting in the input suggests they should be read as independent values rather than interpreted as arithmetic expressions.

CF 105062B - TheForces ORZ

We are given a single small integer $n$, with $1 le n le 8$, and we must output a specific integer that depends only on this value. There are no additional structures, no hidden input, and no multi-step interaction.

CF 105062A - Is It Rated??

We are given two integers, m and d. Think of m as a month number in a calendar year and d as a day of the month. The task is to decide whether this pair can represent a valid calendar date in the simplified world implied by the problem.

CF 105062E - Fixing Chaos

The problem describes a sequence of special values called “chaos points,” indexed starting from 1. We are given a small index $n$, and we must output the value associated with the $n$-th position in this sequence.

CF 105062D - Important Memories

The input describes a single integer $n$, constrained to a very small range from 1 to 6. There is no additional structure, no secondary parameters, and no hidden dataset implied by the statement. The task is to produce a single integer output based on this value.
