Mike has a sequence A = [a1, a2, ..., an] of length n. He considers the sequence B = [b1, b2, ..., bn] beautiful if the gcd of all its elements is bigger than 1, i.e. <image>.
Mike wants to change his sequence in order to make it beautiful. In one move he can choose an index i (1 ... | Step 1: To solve this problem, we need to check if the sequence is beautiful by finding the greatest common divisor (gcd) of all its elements and if it's greater than 1.
