Solution: Find the Kth Largest Integer in the Array

Understand how to solve the problem of finding the kth largest integer in an array of string numbers by applying the top k elements pattern. Learn to implement a min heap to track the largest elements, optimize time complexity to O(n log k), and handle input constraints 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 k $^{th}$ largest integer in the array.

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