Illustrative Drawback and Resolution: Jp Morgan Hackerrank 2025
This part presents a coding problem consultant of the issue stage encountered in JP Morgan’s HackerRank assessments. The issue focuses on environment friendly knowledge manipulation and algorithm design, key expertise valued by the agency. We are going to element the answer, together with its design, implementation, testing, and complexity evaluation.
Drawback Description: Inventory Value Fluctuation
Given a listing of day by day inventory costs, decide the utmost revenue that could possibly be made by shopping for and promoting the inventory on at most two events. You need to purchase earlier than you promote. For instance, if the costs are [10, 22, 5, 75, 65, 80], the utmost revenue can be 75 – 5 + 80 – 75 = 80.
The algorithm ought to deal with instances with no revenue potential, returning 0.
Resolution Design
A brute-force method, checking all potential buy-sell mixtures, would have a time complexity of O(n^4), the place n is the variety of days. That is computationally costly for big datasets. A extra environment friendly method entails dynamic programming. We are able to break the issue into two subproblems: discovering the utmost revenue from the primary buy-sell and the utmost revenue from the second buy-sell.
We are able to use two arrays, one to retailer the utmost revenue ending at every day contemplating just one transaction, and one other to retailer the utmost revenue ending at every day contemplating two transactions.
Algorithm and Pseudocode, Jp morgan hackerrank 2025
The algorithm iterates by way of the costs as soon as, sustaining the utmost revenue for one transaction and the utmost revenue for 2 transactions.Pseudocode:“`perform maxProfitTwoTransactions(costs): n = size(costs) oneTransactionProfit = new array of measurement n, initialized to 0 twoTransactionProfit = new array of measurement n, initialized to 0 minPriceSoFar = costs[0] for i from 1 to n-1: minPriceSoFar = min(minPriceSoFar, costs[i]) oneTransactionProfit[i] = max(oneTransactionProfit[i-1], costs[i] – minPriceSoFar) maxPriceSoFar = costs[n-1] for i from n-2 all the way down to 0: maxPriceSoFar = max(maxPriceSoFar, costs[i]) twoTransactionProfit[i] = max(twoTransactionProfit[i+1], maxPriceSoFar – costs[i] + oneTransactionProfit[i]) return twoTransactionProfit[0]“`
Implementation Particulars
The pseudocode might be readily translated into code utilizing any appropriate programming language (e.g., Python, Java, C++). The implementation would contain creating arrays to retailer the intermediate revenue calculations as described within the pseudocode. Error dealing with must be included to handle instances with invalid enter (e.g., empty worth listing).
Testing
Testing entails making a complete suite of check instances, together with:
- Edge instances: empty enter, single-element enter, all costs the identical.
- Optimistic check instances: varied eventualities with a number of buy-sell alternatives leading to optimistic revenue.
- Destructive check instances: eventualities with no revenue potential.
The implementation must be completely examined in opposition to these instances to make sure correctness and robustness.
Time and House Complexity
The algorithm iterates by way of the value listing twice, leading to a time complexity of O(n). The area complexity is O(n) resulting from using two arrays to retailer intermediate revenue calculations. That is considerably extra environment friendly than the brute-force method.
