The problem can be found at the following link: Question Link
My Approach
To solve this problem, I used a greedy approach.
I first created a vector of pairs, where each pair represents the stock price and its corresponding day.
Then, I sorted this vector based on stock prices in ascending order.
Next, I iterated through the sorted vector, calculating the maximum number of stocks that can be bought on each day without exceeding the available budget.
I kept track of the total number of stocks bought, and the remaining budget after each purchase.
Time and Auxiliary Space Complexity
Time Complexity: The time complexity is dominated by the sorting operation, making it
O(n log n)
, where 'n' is the number of stocks.Auxiliary Space Complexity:
O(n)
, where 'n' is the number of stocks, for storing the vector of pairs.
