503 - Next Greater Element II.

Medium

Given a circular integer array nums (i.e., the next element of nums[nums.length - 1] is nums[0]), return the next greater number for every element in nums.

The next greater number of a number x is the first greater number to its traversing-order next in the array, which means you could search circularly to find its next greater number. If it doesn’t exist, return -1 for this number.

Example 1:

Input: nums = [1,2,1]

Output: [2,-1,2] Explanation:

The first 1’s next greater number is 2;

he number 2 can’t find next greater number.

The second 1’s next greater number needs to search circularly, which is also 2.

Example 2:

Input: nums = [1,2,3,4,3]

Output: [2,3,4,-1,4]

Constraints:

  • 1 <= nums.length <= 104
  • -109 <= nums[i] <= 109
