Answer Posted / shruti

consider home pointer as the starting pointer of the linked
list.
consider temp as the temporary pointer.


temp = home;
while(temp != NULL)
{
if(temp -> next == start)
{
flag = 1;
break;
}
else
flag = 0;
temp = temp -> next;
}

if(flag == 1)
printf("Circular");
else
printf("Not circular");
