Scanner sc = new Scanner(System.in);

System.out.print("\nHow Many Digits : ");
int n=sc.nextInt();

int[] a = new int[n];
int d = 0,p = n-1;

System.out.print("\nEnter The Binary Number : ");

for(int i=0;i<n;i++)
{
a[i] = sc.nextInt();
}

for(int j=0;j<n;j++)
{
int q = (int)Math.pow(2,p);
d = d + a[j]*q;
p--;
}

System.out.println("\nDecimal Number : "+d+"\n");
    }
}
