## Find Second largest element in an array using C Programming

Updated on 12-Jan-2023 0:25:36
Given an array of integers, our task is to write a program that efficiently finds the second largest element present in the array. Example: Input: arr[] = {12, 35, 1, 10, 34, 1} Output: The second largest element is 34. Explanation: The largest element of the array is 35 and the second largest element is 34 Input: arr[] = {10, 5, 10} Output: The second largest element is 5. Explanation: The largest element of the array is 10 and the second largest element is 5 Input: arr[] =... Read More

## Recursive program to linearly search an element in a given array using C

Given an unsorted array and an element x, search x in given array. Write recursive C code for this. If element is not present, return -1. Approach : The idea is to compare x with the last element in arr[]. If an element is found at the last position, return it. Else recur elmntSrch() for remaining array and element x. Program : /* * Approach : The idea is to compare x with the last element in arr[]. * If an element is found at the last position, return it. * Else recur el... Read More
