Feature #8: Find Intervals

Explore how to find the minimum number of intervals before stock prices increase using a monotonic decreasing stack. Understand the algorithm to track price changes efficiently and implement it for coding interview problems involving stock price predictions.

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 ...
