On this page

Problem Statement

Given a circular integer array nums, return the array containing the next greater number for each element in nums.

A next greater number of a number num is the first greater number than the current number in its traversing-order in the array, which means you could search circularly to find its next greater number. If the next greater element doesn't exist, return -1 for the particular number number.

Examples

  • Example 1:
    • Input: nums = [2, 1, 2, 4, 3]
    • Expected Output: [4, 2, 4, -1, 4]
    • Justification: For `2
