prolog delete element from list

To delete an element from a list in Prolog, you can use the built-in predicate select/3. Here's an example of how you can use it:

delete_element(Element, List, NewList) :-
    select(Element, List, NewList).

In the above code, Element is the element you want to delete, List is the original list, and NewList is the resulting list after the element is deleted. The select/3 predicate will remove the first occurrence of Element from List and unify the result with NewList.

Here's an example usage:

?- delete_element(3, [1, 2, 3, 4, 5], NewList).
NewList = [1, 2, 4, 5].

In this example, we are deleting the element 3 from the list [1, 2, 3, 4, 5], resulting in the list [1, 2, 4, 5].

You can use this code as a starting point and modify it according to your specific needs. Let me know if you have any further questions.
