Join For FreeIn mathematics an automorphic number (sometimes referred to as a circular number) is a number whose square "ends" in the same digits as the number itself.
For example,
52 = 25,
62 = 36,
762 = 5776,
and 8906252 = 793212890625,
so 5, 6, 76 and 890625 are all automorphic numbers.
And the logic behind :
int n=56;
int d=1; int i;
for(i=n;i>0;i=i/10)
{
d=d*10;
}
if((n*n)%d==n)
{
System.out.println(n+"\t"+"is Automorphic Number");
}
else
{
System.out.println(n+"\t"+"is not Automorphic Number");
}
}
