Problem Brief
Selecting Stocks
INTERNOA
An investor has saved some money and wants to invest in the stock market. There are a number of stocks to choose from, and they want to buy at most 1 share in any company. The total invested cannot exceed the funds available. A friend who is a stock market expert has predicted the values of each stock after 1 year. Determine the maximum profit that can be earned at the end of the year assuming the predictions come true.
Function Description
Complete the function selectStock in the editor below. The function should return an integer that denotes the maximum profit after one year.
selectStock has the following parameter(s):
- 1.
saving: amount available for investment - 2.
int currentValue[n]: the current stock values - 3.
int futureValue[n]: the values of the stocks after one year
1Example 1
Input
saving = 250, currentValue = [175, 133, 109, 210, 97], futureValue = [200, 125, 128, 228, 133]
Output
55
Explanation
To maximize profits, the investor should buy stocks at indices 2 and 4 for an investment of 109 + 97 = 206. At the end of the year the stocks are sold for 128 + 133 = 261, so total profit is 261 - 206 = 55.
