Feature #8: Find Intervals

Explore how to determine the minimum number of future intervals before a stock price increase using predicted price data. Learn to implement and apply a monotonic decreasing stack in Rust to solve this problem efficiently, preparing you for coding interview questions related to time series and prediction intervals.

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, we ...

Solution

We are given an ...
