The number, 197, is called a circular prime because all rotations of the digits: 197, 971, and 719, are themselves prime.
There are thirteen such primes below 100: 2, 3, 5, 7, 11, 13, 17, 31, 37, 71, 73, 79, and 97.
Find the number of circular primes below n, where n is between 100 and 1000000. Begin by entering the number.
NOTE: Circular Primes individual rotation can exceed n.
