Illustrative Drawback and Answer: Jp Morgan Hackerrank 2025
This part presents a coding problem consultant of the problem stage encountered in JP Morgan’s HackerRank assessments. The issue focuses on environment friendly knowledge manipulation and algorithm design, key abilities valued by the agency. We’ll element the answer, together with its design, implementation, testing, and complexity evaluation.
Drawback Description: Inventory Worth Fluctuation
Given an inventory 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. It’s essential to purchase earlier than you promote. For instance, if the costs are [10, 22, 5, 75, 65, 80], the utmost revenue could be 75 – 5 + 80 – 75 = 80.
The algorithm ought to deal with instances with no revenue doable, returning 0.
Answer Design
A brute-force method, checking all doable 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 includes 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 via the costs as soon as, sustaining the utmost revenue for one transaction and the utmost revenue for 2 transactions.Pseudocode:“`operate maxProfitTwoTransactions(costs): n = size(costs) oneTransactionProfit = new array of dimension n, initialized to 0 twoTransactionProfit = new array of dimension 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 right 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 could 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 includes making a complete suite of check instances, together with:
- Edge instances: empty enter, single-element enter, all costs the identical.
- Constructive check instances: varied situations with a number of buy-sell alternatives leading to constructive revenue.
- Damaging check instances: situations with no revenue doable.
The implementation must be totally examined in opposition to these instances to make sure correctness and robustness.
Time and House Complexity
The algorithm iterates via the worth listing twice, leading to a time complexity of O(n). The area complexity is O(n) as a consequence of using two arrays to retailer intermediate revenue calculations. That is considerably extra environment friendly than the brute-force method.
