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