Stock Picker (Buy low, sell high)

This project aims to buy hypothetical stocks (integers) at their lowest value and sell them at their highest value.

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."

How It Works

Instead of comparing profits throughout the iteration, I instead opted to collect nested arrays of lows and highs:
[[low_price, high_price], [low_price, high_price]]

Then the program calculates the profit of each pair and returns the pair with the highest amount of profit.
