Problem

Write a function that accepts a string argument and removes duplicate characters that are neighbors. If the new string also has duplicate neighbors, those should be removed also.

reduce_dups('abb') => "a"
reduce_dups('abba') => ""
reduce_dups('aba') => "aba"

The Problem

Suppose we could access yesterday's stock prices as an array, where:

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

Write an efficient function that takes stockPricesYesterday and returns the best profit I could have made from 1 purchase and 1 sale of 1 Apple stock yesterday.
