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.
\n
Example 1:
\n\nInput: nums = [1,0,2]
\n\nOutput: [0,1,2]
\n\nExplanation:
\n\n\n\n
The lexicographically smallest permutation with minimum cost is [0,1,2]
. The cost of this permutation is |0 - 0| + |1 - 2| + |2 - 1| = 2
.
Example 2:
\n\nInput: nums = [0,2,1]
\n\nOutput: [0,2,1]
\n\nExplanation:
\n\n\n\n
The lexicographically smallest permutation with minimum cost is [0,2,1]
. The cost of this permutation is |0 - 1| + |2 - 2| + |1 - 0| = 2
.

Constraints:
\n\n2 <= n == nums.length <= 14

is a permutation of [0, 1, 2, ..., n - 1]
