Project Euler Tribute Problem I created
In the given file, data.txt, what is the largest prime number consisting of all prime digits? For this problem we will allow 1 to be considered prime. We will call this the "Hannah Prime"
Each line of the file is seperate: do not continue a possible prime from one line to the next.
For example: 23431720983 contains the prime number 317 that consists of all prime digits (1 is considered a prime digit here)
