How to print all distinct pairs from array with specific difference between them in C#

Answer 1

using System;
 
class Program
{
     static void printPairsWithSpecificDifference(int []arr, int difference) { 
        int size = arr.Length; 
         
        for (int i = 0; i < size; i++) {  
            for (int j = i + 1; j < size; j++) {
                if (arr[i] - arr[j] == difference || arr[j] - arr[i] == difference) {
                    Console.WriteLine(arr[i] + " " + arr[j]);
                }
            }
        } 
    } 
    static void Main() {
        int []arr = {25, 16, 8, 12, 20, 17, 0, 4, 21, 26}; 
        int difference = 4; 
 
        printPairsWithSpecificDifference(arr, difference); 
    }
}
 
 
 
/*
