Remove part in Haskell

In Haskell, you can remove a part of a string using the Data.List module. There are several functions available in this module that allow you to manipulate strings. One function that can be used to remove part of a string is delete.

The delete function removes the first occurrence of a substring from a string. Here's an example:

import Data.List
removeString :: String -> String

removeString str = delete "world" str
main = do

  let str = "hello world"

  putStrLn (removeString str)

In this example, the removeString function removes the substring "world" from the given string using the delete function. The output of this program will be "hello ".

Another function that can be used to remove part of a string is take. The take function returns the first n characters of a given string. Here's an example:

removeChars :: Int -> String -> String
removeChars n str = drop n str
main = do

  let str = "hello world"

  putStrLn (removeChars 5 str)

In this example, the removeChars function removes the first n characters of the given string using the drop function. The output of this program will be " world".
