Your friend has recently learned about coprime numbers. a pair of numbers {a, b} is called coprime if the maximum number that divides both a and b is equal to one. your friend often comes up with different statements. he has recently supposed that if the pair (a, b) is coprime and the pair (b, c) is coprime, then the pair (a, c) is coprime. you want to find a counterexample for your friend's statement. therefore, your task is to find three distinct numbers (a, b, c), for which the statement is false, and the numbers meet the condition l ≤ a < b < c ≤ r. more specifically, you need to find three numbers (a, b, c), such that l ≤ a < b < c ≤ r, pairs (a, b) and (b, c) are coprime, and pair (a, c) is not coprime.
