Test case 2: In the given sequence of numbers, number 10 is the largest element. Input format : 2) All the elements of the array are pairwise distinct. So, we return -1. Write a function named getSecondLargest. You have been given a random integer array/list(ARR) of size N. You have been required to push all the zeros that are present in the array/list to the end of it. Consider the array {2,1,5,6,3,8} and 'K' = 3, the sorted array will be {8, 6, 5, 3, 2, 1}, and the 3rd largest element will be 5. The approach is to traverse the array twice. Now its top element will be the largest element, so we will pop the top element. You have been given a random integer array/list(ARR) of size N. You are required to find and return the second largest element present in the array/list. Output Format : This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. However, since all the elements are the same, the second largest element does not exist. Code navigation not available for this commit.
