delete a as haskell

To delete an element from a list in Haskell, you can use the delete function from the Data.List module. The delete function takes two arguments: the element you want to delete and the list from which you want to delete the element. It returns a new list with the element removed.

Here's an example of how you can use the delete function in Haskell:

import Data.List

main :: IO ()
main = do
  let myList = [1, 2, 3, 4, 5]
  let updatedList = delete 3 myList
  print updatedList

In this example, the delete 3 myList expression removes the element 3 from the list myList. The resulting list, updatedList, is then printed, which will output [1, 2, 4, 5].

Please note that the delete function removes only the first occurrence of the specified element. If the element appears multiple times in the list, only the first occurrence will be deleted.

I hope this helps!
