# 24 Parser Combination

|
## 24.3 Parsing practise
|

## 24.4 Exercise: Unit of Success
|
||
|
|
|
||
|
|
`(>>)` is actually `(*>)` from `Applicative` and `Applicative` also has `(<*)`
|
||
|
|
which has type `Applicative f => f a -> f b -> f a` So the solution here is:
|
||
|
|
`integer <* eof`
|
||
|
|
|
||
|
|
## 24.6 Exercise: Try Try
