WebIntroduction. In this article, we will solve Leetcode 496 using Java. We will solve it using a stack data structure.; Problem Statement. The next greater element of some element x in an array is ... WebThe next greater element of an element x in the array is the first larger number to the next of x. In a circular array, the indices will wrap around as if it were connected end-to-end. In other words, the end of the array wraps around to the start of the array. Therefore, we can search circularly to find the next greater number. WebNov 9, 2024 · After that, we check the size of the stack. If the stack isn’t empty, the top element in the stack is smaller than , and thus it’s the next smaller for the current value.
