In fact, Haskell builds all lists this way by consing all elements to the empty list, [].The commas-and-brackets notation are just syntactic sugar.So [1,2,3,4,5] is exactly equivalent to 1:2:3:4:5:[]. Folds over lists consist of three elements - the list to fold over, some accumulator function f and an initial value..

The overall function has to take an input text file with strings on different lines, then return an ASCII-sorted list of each unique string and the lines that it is located on.

I am a happy advanced beginner in Haskell, currently learning full time at home following along several books, learning category theory too and documenting the learning progress.

Programming in Haskell by Graham Hutton exercises. It's for a portion of my homework, but I'm not just posting the exact question. Contribute to arcomber/haskell development by creating an account on GitHub. Input: reverse([1,3,5]++[2,4,6]) Output: [6,4,2,5,3,1] [6,4,2,5,3,1]

var list1 = new List(){1,2,3}; var list2 = new List(){4,5,6}; var list3 = list1.Concat(list2); In Haskell, lists are what Arrays are in most other languages.
