In Haskell, you can check if an element is present in an array using the elem function.
The syntax for checking if an element is in an array is as follows:
elem :: (Eq a) => a -> [a] -> Bool
The first argument is the element to check for, and the second argument is the array to search in. The function returns True if the element is present in the array, and False otherwise.
Here's an example of checking if an array includes a specific element:
-- check if the number 3 is in the array
containsThree = elem 3 [1, 2, 3, 4, 5]
-- containsThree = True
-- check if the letter 'c' is in the array
containsC = elem 'c' ['a', 'b', 'd', 'e']
-- containsC = False
In the first example, the array [1, 2, 3, 4, 5] includes the element 3, so containsThree is True. In the second example, the array ['a', 'b', 'd', 'e'] does not include the element 'c', so containsC is False.
