answers :: Map Integer (IO String) Source #
Answers to Euler problems.
The answers to Project Euler problems are all numeric, but the type
here is String
rather than Integer
because in some cases the answer
is semantically a "list of digits" rather than an integer, which may
be an important distinction if the first digit of an answer is zero.
Most of the answers are pure, but IO
is allowed because some problems
involve reading input data from files.
