http://snipplr.com/view/68872/palindrome-check-in-c/
A palindrome is a string that reads the same both backwards and forwards. Famous examples are "Madam I'm Adam" or "Able was I ere I saw Elba". This function checks that a given string reads the same backwards and forwards. (requires including stdbool.h) ]]>Sun, 02 Dec 2012 12:43:58 GMThttp://snipplr.com/view/68872/palindrome-check-in-c/(Haskell) Linked List in C - rtperson

http://snipplr.com/view/68840/binary-search-in-haskell/
Not the best binary search implementation -- it really should return a Maybe, Nothing if value not found and Just value if found -- but it was a quick experiment for an evening, and it was cool to see how easily it translated from Java to Haskell. ]]>Fri, 30 Nov 2012 14:16:50 GMThttp://snipplr.com/view/68840/binary-search-in-haskell/(Haskell) Simultaneous filter and map - deepsoul
http://snipplr.com/view/59474/simultaneous-filter-and--map/
The `filtermap` functional below allows to perform the standard `map` and `filter` operations in one go. The mapping function has to return a `Maybe` monad, and values of `Nothing` are filtered out. ]]>Thu, 06 Oct 2011 07:53:01 GMThttp://snipplr.com/view/59474/simultaneous-filter-and--map/(Haskell) Haskell 99 Problems - Problem 23 - rtperson

Problem 18: Extract a slice from a list.
Given two indices, i and k, the slice is the list containing the elements between the i'th and k'th element of the original list (both limits included). Start counting the elements with 1.
Example:
*Main> slice ['a','b','c','d','e','f','g','h','i','k'] 3 7
"cdefg
