Simple code to write their own
Make a judge whether prime function, and then from the known this 3 or 11, respectively to the size of two direction, cycle to find prime Numbers good

Or if you know the range, such as 100, within the early put all prime number calculated in an array, and then find the same

It is not difficult, write their own code
