You are given an integer array order of length n and an integer array friends.
order contains every integer from 1 to n exactly once, representing the IDs of the participants of a race in their finishing order.friends contains the IDs of your friends in the race sorted in strictly increasing order. Each ID in friends is guaranteed to appear in the order array.Return an array containing your friends' IDs in their finishing order.
\n\n\n
Example 1:
\n\nInput: order = [3,1,2,5,4], friends = [1,3,4]
\n\nOutput: [3,1,4]
\n\nExplanation:
\n\nThe finishing order is [3, 1, 2, 5, 4]. Therefore, the finishing order of your friends is [3, 1, 4].
Example 2:
\n\nInput: order = [1,4,5,3,2], friends = [2,5]
\n\nOutput: [5,2]
\n\nExplanation:
\n\nThe finishing order is [1, 4, 5, 3, 2]. Therefore, the finishing order of your friends is [5, 2].
\n
Constraints:
\n\n1 <= n == order.length <= 100order contains every integer from 1 to n exactly once1 <= friends.length <= min(8, n)1 <= friends[i] <= nfriends is strictly increasing给你一个长度为 n 的整数数组 order 和一个整数数组 friends。
order 包含从 1 到 n 的每个整数，且 恰好出现一次 ，表示比赛中参赛者按照 完成顺序 的 ID。friends 包含你朋友们的 ID，按照 严格递增 的顺序排列。friends 中的每个 ID 都保证出现在 order 数组中。请返回一个数组，包含你朋友们的 ID，按照他们的 完成顺序 排列。
\n\n\n\n
示例 1：
\n\n输入：order = [3,1,2,5,4], friends = [1,3,4]
\n\n输出：[3,1,4]
\n\n解释：
\n\n完成顺序是 [3, 1, 2, 5, 4]。因此，你朋友的完成顺序是 [3, 1, 4]。
示例 2：
\n\n输入：order = [1,4,5,3,2], friends = [2,5]
\n\n输出：[5,2]
\n\n解释：
\n\n完成顺序是 [1, 4, 5, 3, 2]。因此，你朋友的完成顺序是 [5, 2]。
\n\n
提示：
