Writing programming interview questions hasn't made me rich yet ... so I might give up and start trading Apple stocks all day instead.

First, I wanna know how much money I could have made yesterday if I'd been trading Apple stocks all day.

So I grabbed Apple's stock prices from yesterday and put them in a list called stock_prices, where:

The indices are the time (in minutes) past trade opening time, which was 9:30am local time.
The values are the price (in US dollars) of one share of Apple stock at that time.
So if the stock cost $500 at 10:30am, that means stock_prices[60] = 500.
