A team of developers and entrepreneurs are working on the idea of BorrowMyKitty, a new platform to connect cat owners with trusted local people who could share the care of the cat. They are considering several options on how cat owners could connect to potential carers and what the revenue model of the platform could be.
1. Briefly describe your recommendation about the potential operation of BorrowMyKitty using the business model concept.
2. The team has asked you to make three recommendations on ways in which the organisation could use big data and data analytics to enhance the success of the platform.
Given two stacks with their standard operations (pop, push, isEmpty, size), implement a queue with its standard operations (enqueue, dequeue, isEmpty, size).
There should be two versions of the solution.
Version A: The queue should be efficient when enqueuing an item; and Version B: The queue should be efficient when dequeuing an item.
1. Suppose you have been working with an organization called 'Money Traders' for the past few years. The organization is into the money trading business. Your manager assigned you a task. For a given array of stock's prices for N days, find the stock's span for each day.
The span of the stock's price today is defined as the maximum number of consecutive days(starting from today and going backwards) for which the price of the stock was less than today's price.
For example, if the price of a stock over a period of 7 days are [100, 80, 60, 70, 60, 75, 85], then the stock spans will be [1, 1, 1, 2, 1, 4, 6].
Explanation:
On the sixth day when the price of the stock was 75, the span came out to be 4, because the last prices (including the current price of 75) were less than the current or the sixth day's price.
Similarly, we can deduce the remaining results.
You have to return an array of spans corresponding to each day's stock's price.
