Solution: Find the Kth Largest Integer in the Array

Explore how to find the kth largest integer in an array of string numbers by applying the top K elements pattern. Learn to maintain the k largest values using a min heap, optimize performance to O(n log k) time complexity, and return correct results 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  ...
