To locate an element in Haskell, you can use the elem function.

The syntax is:

elem :: (Eq a) => a -> [a] -> Bool

This function takes two arguments: the first argument is the element you want to locate, and the second argument is the list where you want to search for the element.

Here's an example:

myList = [1, 2, 3, 4, 5]
x = 3

if elem x myList
  then putStrLn "Found"
  else putStrLn "Not found"

This code will output "Found" because the element "3" is present in the list "myList".
