    932 - Beautiful Array\.

    Medium

    An array nums of length n is beautiful if:

    • nums is a permutation of the integers in the range [1, n].

    • For every 0 <= i < j < n, there is no index k with i < k < j where 2 * nums[k] == nums[i] + nums[j].

    Given the integer n, return any beautiful array nums of length n. There will be at least one valid answer for the given n.

    Example 1:

    Input: n = 4

    Output: 2,1,4,3

    Example 2:

    Input: n = 5

    Output: 3,1,2,5,4

    Constraints:

    • 1 <= n <= 1000
