Description

Write a Java program to find the largest two elements in an array

Input: arr[] = {12, 13, 1, 10, 34, 1}
Output: The largest two elements are 34 and 13

Input: arr[] = {10, 5, 10}
Output: The largest two elements are 10 and 5

Input: arr[] = {10, 10, 10}
Output: The largest two elements are 10 and 10
