## Description
|
|||
|
|
<section id="description"> Число 197, называется круговым простым, поскольку все повороты цифр: 197, 971 и 719 сами по себе являются первыми. Есть тринадцать таких простых чисел ниже 100: 2, 3, 5, 7, 11, 13, 17, 31, 37, 71, 73, 79 и 97. Сколько круговых простых чисел ниже n, тогда как 100 <= n < = 1000000? </section>
