Aw drat. I was going to submit the n'th prime problem until I saw this.
Sadly, I see there are too few test cases, and the problem is too easy to cook.
why 'nthprime' not allowed?
Another great problem!
This solution doesn't use any of the built-in MATLAB functions primes() or isprime(). It works for all integers N > 0, and requires only (N^0.75) iterations.
I do not know how the size are computed. Would someone please tell me?. Thanks in advance.
