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 –
In this tutorial, I am going to discuss what is singleton design pattern, Why and when to use singleton design pattern in php.
