![How to Get [Int] Instead Of [[Int]] Haskell? preview](https://cdn.blogweb.me/1/65fe7ca1dac7dd4d1fd90aaa_e1c8f0914b.png)
4 min readIn Haskell, if you want to obtain a single integer value instead of a list of integers, you can use the head function to extract the first element from the list. For example, if you have a list containing an integer x, you can write "head [x]" to get x as a single integer instead of [x] as a list of integers. However, keep in mind that using head directly on an empty list will result in an error, so it's important to make sure the list is not empty before using this approach.
