Solution: Find the Kth Largest Integer in the Array

Explore how to efficiently find the kth largest integer represented as strings by using a min heap. Understand heap operations and apply the top K elements pattern to manage and return the kth largest number without sorting the entire array.

Statement

Given an array of strings, nums, where each string represents an integer without leading zeros, and an integer k, your task is to find and return the string representing the kth^{th} largest integer in the array.

Note: Treat duplicate integers as distinct entities. For instance, if nums =[“2”, “3”, “3”]= [\text{\lq\lq2\rq\rq, \lq\lq3\rq\rq, \lq\lq3\rq\rq]}, the first largest integer is “3”\text{\lq\lq3\rq\rq}, the second largest is also “3”\text{\lq\lq3\rq\rq}, and the third largest is  ...
