Fast? I have made no attempt to make my solutions fast, and the slowest one gives
real 0m0.059s
user 0m0.007s
sys 0m0.000s
using the Linux "time" command. All of them have a user time < 10 ms. Almost all
the real time is doing I/O. And there are no timing requirements.
"Fast" should not be something anyone is worrying about.
