Modules

Modules

1. The modules in haskell are collections of related functions, types and typeclasses. And those are part of a collection(A program) where there is a main module that loads up the other modules and uses them with the functions to run something.

2. Data.List

   • Some of the List transformations and Sublist
     • "Intersperse takes an element and a list and then puts that element between each pair of elements in the list"
     • "Transpose is for transponse a list of lists"
     • splitAll takes a number and a list. It then splits the list in many elements, returning the resulting two list in a tuple
     • "dropWhile" drops the elements when the predicate is true. Once it changes, it returns the rest of the list

3. Data.Char

   • Some of the character classification
     • "isLetter" similar to "isAlpha" checks whether a character is a letter
     • "isControl" checks wheter a character is a control character
     • "isDigit" checks whether a character is lower-cased"

4. Data.Set

   • Contructions
     • "fromList" function works by taking ta list a converting it into a set
     • Difference function looks at the letters in the first and also the same which are not in the second
