Once upon a time, in a quaint village surrounded by lush forests, there lived a toucan named Owen, who was also a mathematician. Owen, being quite the playful bird, wrote down an array on a piece of paper, consisting of a permutation of positive integers from to . Then, he wrote down an array of length on the paper. The array is constructed by taking the Greatest Common Divisor (GCD) of each element and the corresponding element . Namely, . However, he purposely accidentally lost the paper and cannot remember what the arrays and were. Fortunately, he still remembers that there are exactly unique integers in array . Can you please help him find a possible array ?
Note: A permutation of length is an array consisting of distinct integers from to in any order.
