Understanding the Next Greater Element I I Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
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.
