        }

        int n = arr.length;
        int temp = 0;
        for(int i = 0; i < n; i++){
            for(int j=1; j < (n-i); j++){
                if(arr[j-1] < arr[j]){
                    //swap elements
                    temp = arr[j-1];
                    arr[j-1] = arr[j];
                    arr[j] = temp;
                }

            }
