# Longest Streak

**Question:** A streak is the consecutive reoccurance of an event. For example, if you flip a coin twice and it appears head both times, then there is a streak of two heads. Define a function 'streak' that returns the length of the longest streak of a list, as an integer.

### Example

```
``````
q)streak `h`t`h`t`h`h`h`t`t`h`t
