Transaction Balancing

In a financial tracking app, you need to balance expenditures over a week. You will be given the net balance amount for each day and need to report the total balance up to any day. Write a program that reads the net balances for 7 days and answers multiple queries regarding total balance by day. For example, given the input: 7 100 -50 200 -100 50 25 75 4 1 2 5 7 You should output: 100 50 50 125 This is because the cumulative balances for day 1, day 2, day 5, and day 7 are 100, 50, 50, and 125 respectively.
