Solution: Find the Kth Largest Integer in the Array

Explore how to identify the kth largest integer in an array of strings without sorting the entire list. This lesson teaches you to implement a min heap that maintains the k largest elements dynamically, optimizing time and space complexity for the solution.

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  ...
