Smallest Number in Infinite Set leetcode link In this article, we will explore the design and implementation of the SmallestInfiniteSet class. This class allows you to manage an infinite set of positive integers with two primary operations: popping the smallest element and adding elements back into the set. By using a combination of a min-heap and a set, we ensure that these operations are efficient. Let’s begin by looking at the code.

Finding the Kth Largest Element Using a Min Heap The problem of finding the Kth largest element in an unsorted list is a common interview question. A common and efficient approach to solve this problem is using a min heap of size K. Concept The key idea is that the Kth largest element is the smallest element in a list of the K largest elements of the array. Example Given the array nums = [3, 2, 1, 5, 6, 4] and k = 2, we need to find the 2nd largest element.
