Feature #8: Find Intervals

Understand how to solve stock price interval problems by using a monotonic decreasing stack to find when prices will rise next. Learn to create an array indicating minimum intervals until a price increase, with an efficient O(n) time solution.

Description

We are given the price predictions, prices, of a stock over a future time window. We are interested in making a profit by selling the stock at a higher price.

There are n intervals in the time window, where each ithi^{th} interval represents a stock’s predicted price for that interval. Our goal is to return an array, intervals, such that intervals[i] is the minimum number of intervals after the ith interval when the price will increase. If there is no time interval for which this is possible, ...

Solution

We are given an ...
