How do I filter a list in Haskell?

In Haskell, you can use the filter function to filter elements of a list based on a predicate. For example, filter even [1..10] will return [2,4,6,8,10].

Can you explain how the predicate works in the filter function?

Sure! The predicate is a function that takes an element and returns a Boolean value. If it returns True, the element is included in the result; if False, it is excluded.

What if I want to filter based on a custom condition?

You can define your own predicate function. For example, filter ( x -> x > 5) [1..10] will return [6,7,8,9,10].

Can I use multiple conditions to filter a list?

Yes, you can combine conditions using logical operators. For instance, filter ( x -> x > 2 && x < 8) [1..10] will return [3,4,5,6,7].
