    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; The 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:

    • <code>1 <= nums.length <= 10<sup>4</sup></code>

    • <code>-10<sup>9</sup><= numsi<= 10<sup>9</sup></code>
