I am not familiar with stock prices at all. I really do not understand what I am supposed to do. I am not looking for a solution to the problem. I am asking for someone to explain me better what am I being asked to create. Below is the assignment I am having trouble understanding.
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.
