euler

These are answers for Project Euler mathematical problems in the Plan 9 dialect of C.

I have written these using the 9front operating system, but there is no reason that they shouldn't compile on vanilla Plan 9 or Plan 9 from User Space.

The original math problem's wording is on the top of each .c file as a comment.

I abuse unsigned 64-bit integers where they are not needed because I'm not very concerned with picking optimal data types for numbers in such small programs.

Running mk in each directory should compile an executable which determines the problem's answer. I usually test the answer's speed using the time command on the resulting executable.
