September 2014 1HaskellADay problems and solutions

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
  • September 2nd, 2014: Good morning! Triangle Sums is our #haskell problem for today: No triangles were harmed in the solution of their sum (nor in the summation of their solution)

  • 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? Paid. Or: a constructivist approach reduces the generated sets from 200M+ down to 8 possible solutions That's doable. ... and here is the 'Mr. Clean' version of the solution: fast, and neat. Groovy!
  • September 4th, 2014: Today's #haskell problem: Abacus words 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? Data.Graph FTW! 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 The solution-style to Montley Stew isswimming in list-compression stew
  • September 9th, 2014: King Tut! Our #haskell problem for today is NOT a Pyramid Scheme. Maybe.
  • September 10th, 2014: 'Sed' is 'but(t)' just another word ... in "'laddin" 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!
  • September 11th, 2014: A-plus for you when you solve today's #haskell exercise But an F- (NOT an F# ... geddit?) for /usr/share/dict/words :/ A solution to today's injectInto #haskell problem
  • September 12th, 2014: Today's #Haskell problem comes from She. She who commands you solve it before coding it. So, you know: there it is. Okay, 'thurt' is a word in WHICH Universe? A solution to today's #haskell 'ditto' problem
  • September 15th, 2014: "The name of the game is Connect Four!" and today's #haskell problem as suggested by a tweet from @DrEugeniaCheng. I played Connect 4 against myself and lost! :/ A semi-solution to today's #haskell problem at

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

  • September 18th, 2014: Star (Tuna?) Fish? A radial word-finding/matching game is today's #haskell puzzle. Wait. Quantum...WHAT? A solution to today's #haskell problem using quantum superpositions to solve it. I'm not joking. STAR POWER! A solution for pretty-printing the star-puzzle
  • September 19th, 2014: Continued fractions and dual inversionals are today's #haskell problem It even comes with (thoughts about) flowers. #Ult Today's problem was inspired by a comment, then the main article, from @aperiodical That was some LOOOOOOOONG Division! A solution to today's #haskell problem.
  • September 22nd, 2014: Oh, noes! The 'M'-word! for today's #haskell exercise. Project Eulerproblem 11'M' is for 'Monoid' A solution to today's #haskell problem.
  • September 23rd, 2014: "Oh, the snark bites, with his teeth, dear." MACD Knife ... geddit? Today's #haskell problem is a technical indicator.
  • September 24th, 2014: Jones, Smith, and Brown work at the Bank... but not Mr. Banks.A logic puzzle from 1957 for today's #haskell puzzle A pair of PhDs ( helped to solve today's #haskell problem. Neatly, too, I might add.
  • September 25th, 2014: Corned-beef hashi? No, that's not right, and now I'm hungry! :( Shoot! Well, anyway: today's #haskell problem.
  • September 26th, 2014: HA! I TOLD you we'd be getting to cipher-text! From the 1700's, still: it IS cipher text for today's #haskell problem. Ooh! The Plot Thickens (like pea soup)! "ALLMENHAVING" and "be mis T r U st ed " is a solution to today's problem.
  • September 29th, 2014: Big (Crypto) Generator! Today's #haskell problem is a follow-on to Friday's. Human Error ... WHAT human error? A solution to today's make-your-own-cypto-table #haskell problem
  • September 30th, 2014: "I wanna be a blue-collar man!" Yes, but who, and which occupation? Today's #haskell problem addresses this. Plumber, ... or painter? IDK! TWO-solutions to today's #haskell problem (one of them MAY be correct... :/ )
