CF 105591B - Последовательный треугольник
We are asked whether it is possible to form a triangle whose side lengths are three consecutive natural numbers and whose perimeter equals a given value $p$. A valid triangle in this setting is fully determined by a starting integer $a$.
CF 105591D - Учёные
We are looking at all integers from 1 up to a very large number n. Each integer is treated as a bacterium, and each bacterium is assigned a label equal to its number. Two bacteria are considered similar when the sum of digits of their labels is the same.
CF 105591C - Первое уравнение
We are given a positive integer $n$. We want to count how many ordered quadruples of natural numbers $(a, b, c, d)$ exist such that both pairs satisfy the same sum constraint $a + b = n$ and $c + d = n$, and all four numbers are strictly ordered as $a < c < d < b$.
CF 105591E - Скучная строка
We are given a string consisting of lowercase Latin letters. The string is considered “boring” if it contains any contiguous block where the same character appears at least m times in a row.
