# Project: Stock picker

## Assignment

Implement a method `#stock_picker` that takes in an array of stock prices, one for each hypothetical day. It should return a pair of days representing the best day to buy and the best day to sell. Days start at 0.

```ruby
  > stock_picker([17,3,6,9,15,8,6,1,10])
  => [1,4]  # for a profit of $15 - $3 == $12
```

## **Quick tips**

* You need to buy before you can sell
* Pay attention to edge cases like when the lowest day is the last day or the highest day is the first day.
