Solution: Find the Kth Largest Integer in the Array

Explore how to efficiently identify the kth largest integer in an array of strings by using a min heap data structure. This lesson helps you understand maintaining the top K elements and optimizing search without sorting the entire array, improving your problem-solving skills for coding interviews.

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  ...
