Max Reserve Balance Adjustment

Given a platform identifier and a list of transactions, for accounts other than the platform identifier, if the current balance is less than zero, you can borrow funds from the platform identifier to cover the shortfall. Output three results: max reserve, rejected transaction list, and users with non-zero balances and their balances. Example input with platform_id as acct_123: account_name, timestamp, currency, amount acct_123,1,usd,1000 acct_321,3,usd,400 acct_321,4,usd,-500 Output: max_reserve = 100, rejected_transaction = [], acct_123 and 900 Example Input platform_id: acct_123 account_name, timestamp, currency, amount acct_123,1,usd,1000 acct_321,3,usd,400 acct_321,4,usd,-500
