These are Haskell translations of Ninety-Nine Lisp Problems,
which are themselves translations of Ninety-Nine Prolog Problems.
If you want to work on one of these, put your name in the block so we know someone's working on it. Then, change n in your block to the appropriate problem number, and fill in the <Problem description>,<example in lisp>,<example in Haskell>,<solution in haskell> and <description of implementation> fields. Then be sure to update the scoreboard on this page to indicate that we have a solution!
1 The problems
These problems have been split into 11 parts, for ease of access.
- Questions 1 to 10: Lists
- Questions 11 to 20: Lists, continued
- Questions 21 to 28: Lists again
- Questions 31 to 41: Arithmetic
- Questions 46 to 50: Logic and codes
- Questions 54A to 60: Binary trees
- Questions 61 to 69: Binary trees, continued
- Questions 70B to 73: Multiway trees
- Questions 80 to 89: Graphs
- Questions 90 to 94: Miscellaneous problems
- Questions 95 to 99: Miscellaneous problems, continued
(Though the problems number from 1 to 99, there are some gaps and some additions marked with letters. There are actually only 88 problems.)
