nixCraft 🐧A Perl programmer is asked to write a script to find all the prime numbers. They finish in 5 minutes. "How did you do it so fast?" asks their coworker. "I just used the is_prime function," they reply. "But Perl doesn't have an is_prime function!" yells back the coworker. The Perl programmer laughs. "I know. I wrote it in three lines."
peter honeyman@nixCraft i don’t really get the joke — it’s not hard to write a three-line is_prime function
reinierl@peterhoneyman @nixCraft I'm not a mathematician, but I am under the impression that "find all the prime numbers", implying that this has to happen happen within finite time and space, is an impossible requirement. Not sure if that's the point of the joke or just sloppiness.
