Can you write a function to calculate the total value of a portfolio given an array of stocks and their respective quantities?
JP Morgan is heavily involved in asset management and investment banking, making portfolio management systems crucial. This question assesses your ability to work with data structures and algorithms relevant to financial applications.
Step 1: Understand the problem clearly by discussing input and output requirements.
Step 2: Define the data structure to hold stock information, like a class or dictionary.
Step 3: Write the core logic to loop through the provided stocks and calculate the total value based on their quantities.
Step 4: Test the function with various test cases to ensure accuracy.
To solve this problem, I would start by defining a function called `calculatePortfolioValue`. This function would take an array of stocks, where each stock is represented as an object containing its price and quantity. I would initialize a variable to hold the total value and iterate through the array, multiplying each stock's price by its quantity and adding it to the total. Finally, I would return the total value. This implementation would be efficient and ensure accuracy for any input size.
Make sure you clarify any assumptions about stock prices and quantities.
Use meaningful variable names to improve code readability.
Consider edge cases, such as an empty portfolio or stocks with zero quantity.
Expect questions related to data structures, algorithms, and real-world scenarios relevant to finance.
Coding style is important as it reflects your attention to detail and professionalism.
