October 2018 1HaskellADay Problems and Solutions

• October 31st, 2018: A Happy Halloween arithmetic puzzle for you Happy Haskellers! 
• October 25th, 2018: Thursday's #haskell problem we have a (Loopful) compiler for BF* Thursday's #haskell solution: A BF* compiler, blocks of code in loops working. 
• October 24th, 2018: Wednesday's #haskell problem: Thus we enter the Turing Tarpit! The solution to Wednesday's #haskell problem is a BF* (loopless) interpreter that prints out "Hello, world!" I didn't think I could reach the pinnacle of programming in my lifetime, yet, here I am. 😎 
• October 19th, 2018: For Friday's #haskell problem we look at patterns in how people define categories: a little knowledge management. 
  
• October 17th, 2018: For Wednesday's #haskell problem we are using Haskell to automate writing a set of SQL INSERT statements. The function addDays to Wednesday's #haskell problem's rescue! 
  
• October 15th, 2018: Monday's #haskell problem is a little asset shell-game. A little Set.union, a little Set.difference, to get today's #haskell solution. 
• October 9th, 2018: Tuesday's #haskell problem: given a set of ids and our knowledge store from yesterday, determine the status of the new ids. Tuesday's #haskell solution: a Set to determine membership, and a Map to give the result, with a little bit of Frege-logic for fun! 
• October 8th, 2018: Monday's #haskell problem is random screening (okay: predetermined screening). Monday's #haskell solution: indexing into a list often? Consider the Array-type. 
• October 5th, 2018: Friday's #haskell problem we create a workflow to process chunks of files as SQL INSERT statements. And lo! and behold! A #haskell solution to all our problems... or today's problem, anyway.
