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

Answer 1

class CArray {
    printPairsWithSpecificDifference(arr, difference) {
        const size = arr.length;
          
        for (let i = 0; i < size; i++) {        
            for (let j = i + 1; j < size; j++) {
                if (arr[i] - arr[j] == difference || arr[j] - arr[i] == difference) {
                      console.log(arr[i] + " " + arr[j]) 
                }
            }
        } 
    }
}
  
  
const obj = new CArray();
const arr = [25, 16, 8, 12, 20, 17, 0, 4, 21, 26];
const difference = 4;
  
obj.printPairsWithSpecificDifference(arr, difference);
  
  
  
   
/*
run:
     
"25 21"
"16 12"
"16 20"
"8 12"
"8 4"
"17 21"
"0 4"
     
*/
