WebFirstly, The initial is idea is same as editorial (make A and B array elements odd) Secondly, the trie stores the elements of array B in bitwise fashion starting with the Most significant digit at root to Least significant digit. Here, the Trie node stores pointers to two children 0, 1, parent node and count. WebLet f(x, y) = ⌊ n 2x ∗ 3y⌋. It means the number of multiples of 2x ∗ 3y less than or equal to n. Here are the transitions: If your permutation is filled until index i and its gcd is 2x ∗ 3y, you can do one of the following 3 things upon choosing pi + 1: Add a multiple of 2x ∗ 3y. That way, the gcd won't change.
