int a,arm=0,n,temp;
System.out.println("Enter a number:\n");
Scanner obj=new Scanner( System.in);
n=obj.nextInt();
temp=n;
for( ;n!=0;n/=10 )
{
a=n%10; arm=arm+(a*a*a);
}
if(arm==temp)
System.out.println(temp+" is a armstrong number ");
else
System.out.println(temp+" is not a armstrong number ");
}
}
