You are given an integer array nums of length n and an integer array queries.

\n\n

Let gcdPairs denote an array obtained by calculating the GCD of all possible pairs (nums[i], nums[j]), where 0 <= i < j < n, and then sorting these values in ascending order.

\n\n

For each query queries[i], you need to find the element at index queries[i] in gcdPairs.

\n\n

Return an integer array answer, where answer[i] is the value at gcdPairs[queries[i]] for each query.

\n\n

The term gcd(a, b) denotes the greatest common divisor of a and b.

\n\n

 

\n

Example 1:

\n\n
\n

Input: nums = [2,3,4], queries = [0,2,2]

\n\n

Output: [1,2,2]

\n\n

Explanation:

\n\n

gcdPairs = [gcd(nums[0], nums[1]), gcd(nums[0], nums[2]), gcd(nums[1], nums[2])] = [1, 2, 1].

\n\n

After sorting in ascending order, gcdPairs = [1, 1, 2].

\n\n

So, the answer is [gcdPairs[queries[0]], gcdPairs[queries[1]], gcdPairs[queries[2]]] = [1, 2, 2].

\n
\n\n

Example 2:

\n\n
\n

Input: nums = [4,4,2,1], queries = [5,3,1,0]

\n\n

Output: [4,2,1,1]

\n\n

Explanation:

\n\n

gcdPairs sorted in ascending order is [1, 1, 1, 2, 2, 4].

\n
\n\n

Example 3:

\n\n
\n

Input: nums = [2,2], queries = [0,0]

\n\n

Output: [2,2]

\n\n

Explanation:

\n\n

gcdPairs = [2].
