Hey ;)
Could you please comment on my solution? I see the size is much larger than leading solution, but regardless. I would say my solution is lame, because it was taylored for this specific set of conditions (test suite), I would like to make "universal" solution, which could work for random inputs, but this taylored solution seems much easier. What do you think?
Thank you for your opinion :)

Try setting up a loop to test individual values using isprime() that will terminate upon reaching the fifth prime number to prevent an inordinately long loop.
