Description

nput:

We first ask the user to input the number of days n.
Then, the user provides the stock prices for each day as input.
Logic:

The function maxProfit calculates the maximum profit by iterating through the stock prices.
min_price keeps track of the lowest price seen so far.
max_profit is updated if the difference between the current price and the min_price gives a higher profit.
Output:

The program outputs the maximum possible profit.
