A while ago I ended up on a StackOverflow question which I believe could fit under fastest-code category as it's all about killing the idea a C program could beat anything else in speed (here the main competitor is
mawk for text processing with regexes).
As there's already been a wide meta-effect on this question on SO, I'm unsure it would be on-topic there or not, so before writing a challenge about it I have two questions:
- Would it be on-topic (and with which tag ?)
- Is the test system in place (github+travis) valid to classify answers
Side Note: Would the test system be of some interest for other challenges ?
P.S: Tell me if I should copy here parts of the existing SO and Meta-SO questions to ease the understanding (but the subject is quite vast now and I'm afraid making this one too long by overquoting)
