Find the Minimum Cost Array Permutation
You are given an array nums which is a permutation of [0, 1, 2, ..., n - 1]. The score of any permutation of [0, 1, 2, ..., n - 1] named perm is defined as:
score(perm) = |perm[0] - nums[perm[1]]| + |perm[1] - nums[perm[2]]| + ... + |perm[n - 1] - nums[perm[0]]|
Return the permutation perm which has the minimum possible score. If multiple permutations exist with this score, return the one that is lexicographically smallest among them.
Example 1
Input
nums = [1,0,2]Output
[0,1,2]The lexicographically smallest permutation with minimum cost is
[0,1,2], and the cost is |0 - 0| + |1 - 2| + |2 - 1| = 2.Example 2
Input
nums = [0,2,1]Output
[0,2,1]The lexicographically smallest permutation with minimum cost is
[0,2,1], and the cost is |0 - 1| + |2 - 2| + |1 - 0| = 2.Constraints
- 2 <= n == nums.length <= 14
- nums is a permutation of [0, 1, 2, ..., n - 1].
