Triple Accessing Element

Question

If in Haskell I had a tuple: ``` x = (1, 2) ``` I could use fst x to retrieve 1 and snd x to retrieve 2 I was wondering, if I had a triple: ``` y = (1, 2, 3) ``` is there a similar function I could use?

Accepted Answer

You need to write your own extractor functions:

```
extractFirst :: (a, b, c) -> a
extractFirst (a,_,_) = a
```

The `fst` and `snd` functions are only applicable for a tuple i.e `(a, b)`
