Let’s discuss a problem to find the second largest number in an array.
Given an unsorted array of integers, write a code to find the second largest number in an array.
For example –
Input – arr[] = { 4, 1, 5, 2, 8, 0, 3, 55}
Output – 8
The second max element in this array is 8.
Before checking the solution, let’s think for a moment, how do you approach this problem? There are multiple ways to solve this problem. Which approach you prefer and why? At the end of this tutorial, I have shared the link to the video tutorial.
In this tutorial, I am going to cover following topics –
Write a c program to find missing number in array. Given an array of numbers from 1 to n. The array is sorted. One number is missing from an array. You have to write a c code to find the missing number from an array. Also ,there is no duplicates in an array. This type of questions is generally asked in technical interviews.
