## Description
|
||
|
|
<section id="description"> O número, 197, é chamado de primo circular porque todas as rotações dos dígitos: 197, 971 e 719 são elas próprias primárias. Existem treze primos abaixo de 100: 2, 3, 5, 7, 11, 13, 17, 31, 37, 71, 73, 79 e 97. Quantos primos circulares estão abaixo de n, enquanto 100 <= n < = 1000000? </section>
