Maximum difference between two elements in an Array
Given an array arr[] of N integers, the task is to find the maximum difference between any two elements of the array.
Examples:
Input: arr[] = {2, 1, 5, 3}
Output: 4
|5 – 1| = 4Input: arr[] = {-10, 4, -9, -5}
Output: 14
Approach: The maximum absolute difference in the array will always be the absolute difference between the minimum and the maximum element from the array.
Below is the implementation of the above approach:
C++
// C++ implementation of the approach#include <bits/stdc++.h>using namespace std; // Function to return the maximum// absolute difference between// any two elements of the arrayint maxAbsDiff(int arr[], int n){ // To store the minimum and the maximum // elements from the array int minEle = arr[0]; int maxEle = arr[0]; for (int i = 1; i < n; i++) { minEle = min(minEle, arr[i]); maxEle = max(maxEle, arr[i]); } return (maxEle - minEle);} // Driver codeint main(){ int arr[] = { 2, 1, 5, 3 }; int n = sizeof(arr) / sizeof(arr[0]); cout << maxAbsDiff(arr, n); return 0;} |
Java
// Java implementation of the approachclass GFG { // Function to return the maximum // absolute difference between // any two elements of the array static int maxAbsDiff(int arr[], int n) { // To store the minimum and the maximum // elements from the array int minEle = arr[0]; int maxEle = arr[0]; for (int i = 1; i < n; i++) { minEle = Math.min(minEle, arr[i]); maxEle = Math.max(maxEle, arr[i]); } return (maxEle - minEle); } // Driver code public static void main(String[] args) { int[] arr = { 2, 1, 5, 3 }; int n = arr.length; System.out.print(maxAbsDiff(arr, n)); }} |

// C# implementation of the approach using System; class GFG{ // Function to return the maximum // absolute difference between // any two elements of the array static int maxAbsDiff(int []arr, int n) { // To store the minimum and the maximum // elements from the array int minEle = arr[0]; int maxEle = arr[0]; for (int i = 1; i < n; i++) { minEle = Math.Min(minEle, arr[i]); maxEle = Math.Max(maxEle, arr[i]); } return (maxEle - minEle); } // Driver code public static void Main() { int[] arr = { 2, 1, 5, 3 }; int n = arr.Length; Console.WriteLine(maxAbsDiff(arr, n)); } } // This code is contributed by Ryuga |
PHP
<?php// PHP implementation of the approach // Function to return the maximum// absolute difference between// any two elements of the arrayfunction maxAbsDiff($arr, $n){ // To store the minimum and the maximum // elements from the array $minEle = $arr[0]; $maxEle = $arr[0]; for ($i = 1; $i < $n; $i++) { $minEle = min($minEle, $arr[$i]); $maxEle = max($maxEle, $arr[$i]); } return ($maxEle - $minEle);} // Driver code$arr = array(2, 1, 5, 3);$n = sizeof($arr);echo maxAbsDiff($arr, $n); // This code is contributed// by Akanksha Rai |
