324 - Wiggle Sort II.

Medium

Given an integer array nums, reorder it such that nums[0] < nums[1] > nums[2] < nums[3]....

You may assume the input array always has a valid answer.

Example 1:

Input: nums = [1,5,1,1,6,4]

Output: [1,6,1,5,1,4]

Explanation: [1,4,1,5,1,6] is also accepted.

Example 2:

Input: nums = [1,3,2,2,3,1]

Output: [2,3,1,3,1,2]

Constraints:

  • 1 <= nums.length <= 5 * 104
  • 0 <= nums[i] <= 5000
  • It is guaranteed that there will be an answer for the given input nums.

Follow Up: Can you do it in O(n) time and/or in-place with O(1) extra space?
