Compute transfers to balance account debts

## Problem: Balance accounts by generating transfers You are given a dictionary/map `balances` from `accountId -> netBalance`. - A **positive** balance means the account should **receive** money (is owed money). - A **negative** balance means the account should **pay** money (owes money). - The sum of all balances is guaranteed to be **0**. Produce a list of transfers that will settle all accounts to net 0. ### Output format Return a list of transfers like: - `(fromAccount, toAccount, amount)` where `amount > 0` After applying all transfers: - Every account’s balance becomes exactly `0`. ### Example Input: ```text { A: -5, B: 2, C: 3 } ``` One valid output: ```text [(A, B, 2), (A, C, 3)] ``` ### Notes / constraints - You may return **any** valid set of transfers. - Prefer fewer transfers if possible, but correctness is the priority.
