Account Balance Ledger With Transfers Validation and Platform Credit

Problem: Account Balance Ledger (Stripe-style) You are given a list of transfer/transaction records. Each record contains at least: timestamp: a comparable time value from: sender account to: receiver account amount: a positive integer Tasks Process in chronological order: Sort records by increasing timestamp (if ties, keep input order). Maintain balances per account (initially 0). For each record, subtract amount from from and add amount to to. Validate / reject illegal transfers: Before applying a transfer, check whether it is allowed (e.g., sender has sufficient funds). If not allowed, reject it (apply no balance changes) and continue. Reconciliation extension: 3a: On top of (2), allow a platform/system credit source to temporarily lend money so a transfer can proceed, to be repaid by later incoming funds. 3b: Mentioned by the author but not described; omitted. Output Return/print the final balance for each account (in the required format). Constraints Not provided in the post; candidates are typically expected to clarify N, number of accounts, and ordering of timestamps.
