[erlang-questions] Idiom for multiple case matches
Mon Nov 10 18:27:30 CET 2008
For completeness, I did run some benchmarking. I hesitate to put my name to
my solution, since it was suggested in jest, but I am vindicated because it
performed as expected:
Virding: Run-Time/Wall-Clock: 94/94 milliseconds
Cronqvist: Run-Time/Wall-Clock: 141/141 milliseconds
Mercer: Run-Time/Wall-Clock: 14547/14547 milliseconds
