1HaskellADay: Up, up, and away!

I've taken it upon myself to submit problems, then show the solutions, for @1HaskellADay. I started this work on July 1st, 2014. So the next set of entries serve to collect what I've done, both problems and solutions, and, if a particular day posed a particularly interesting problem, that I solved, or, that I didn't solve, I'll capture that here, too.


The problems are free-form meditations based off the P-99: Ninety-Nine Prolog problems published by Werner Hett (Ooh! Fancy new look!)

September, 2014

  • September 1st, 2014: They tried to kill the Metal...I don't know where I'm going with that. But rock-n-roll with today's #haskell exercise http://lpaste.net/110331
  • September 2nd, 2014: Good morning! Triangle Sums is our #haskell problem for today: http://lpaste.net/110404 No triangles were harmed in the solution of their sum (nor in the summation of their solution) http://lpaste.net/110432

  • September 3rd, 2014: Pay It Forward. What? You didn't think I'd just say: today's #haskell problem is hard and leave it at that, did you? http://lpaste.net/110444 Paid. Or: a constructivist approach reduces the generated sets from 200M+ down to 8 possible solutions http://lpaste.net/110684 That's doable. ... and here is the 'Mr. Clean' version of the solution: fast, and neat. Groovy! http://lpaste.net/110685
  • September 4th, 2014: Today's #haskell problem: Abacus words http://lpaste.net/110494 because MRFE says "I don't like your math problems; I want more word problems"
  • September 5th, 2014: These 'edgy' relationships these days!  Remember when today's #haskell problem didn't involve graph theory? http://lpaste.net/110543 Data.Graph FTW! http://lpaste.net/110571 A solution to today's 4sum #haskell problem, and it didn't require generating 1625702400 solutions!
  • September 8th, 2014: We have puzzles 1 and 5 from the "Montley Stew" problem set for today's #haskell problem http://lpaste.net/110699 The solution-style to Montley Stew is swimming in list-compression stew http://lpaste.net/110750
  • September 9th, 2014: King Tut! http://lpaste.net/110789 Our #haskell problem for today is NOT a Pyramid Scheme. Maybe.
  • September 10th, 2014: 'Sed' is 'but(t)' just another word ... in "'laddin" http://lpaste.net/110833 Today's #haskell problem is mix-n-match words. "But(t) I sed ..." ARG! Enough with the 3rd-grade humor! On with the solution to the mix-n-match words! http://lpaste.net/110859
  • September 11th, 2014: A-plus for you when you solve today's #haskell exercise http://lpaste.net/110862 But an F- (NOT an F# ... geddit?) for /usr/share/dict/words :/ A solution to today's injectInto #haskell problem http://lpaste.net/110891
  • September 12th, 2014: Today's #Haskell problem comes from She. She who commands you solve it before coding it. http://lpaste.net/110925 So, you know: there it is. Okay, 'thurt' is a word in WHICH Universe? A solution to today's #haskell 'ditto' problem http://lpaste.net/110955
  • September 15th, 2014: "The name of the game is Connect Four!" and today's #haskell problem http://lpaste.net/111065 as suggested by a tweet from @DrEugeniaCheng. I played Connect 4 against myself and lost! :/ A semi-solution to today's #haskell problem at http://lpaste.net/111105

  • September 16th, 2014: There's more than one way to slice and dice a matrix for today's #haskell problem http://lpaste.net/111109 (follow-up to yesterday's Connect4) A Hack-n-slash solution to today's diagonal view of matrices. http://lpaste.net/111130 The bonus solution is provided back at the Connect Four answer to make that game complete: http://lpaste.net/111105
  • September 17th, 2014: Do you Yahoo!? Today's #haskell problem: connecting to Yahoo!'s financial webservice http://lpaste.net/111071 I like my java GREEN! http://lpaste.net/111238 (java means 'coffee') A solution to stock webservice #haskell problem.

  • September 18th, 2014: Star (Tuna?) Fish? http://lpaste.net/111216 A radial word-finding/matching game is today's #haskell puzzle. Wait. Quantum...WHAT? http://lpaste.net/111259 A solution to today's #haskell problem using quantum superpositions to solve it. I'm not joking. STAR POWER! http://lpaste.net/edit/111259 A solution for pretty-printing the star-puzzle
  • September 19th, 2014: Continued fractions and dual inversionals are today's #haskell problem http://lpaste.net/111067 It even comes with (thoughts about) flowers. #Ult Today's problem was inspired by a comment, then the main article, from @aperiodical http://aperiodical.com/2013/11/from-the-mailbag-dual-inversal-numbers/#comment-611141 That was some LOOOOOOOONG Division! http://lpaste.net/111314 A solution to today's #haskell problem.
