Central Banking Algorithm

Design an algorithm to simulate a central banking operation. The goal is to calculate the net balance across all participating banks and then facilitate a single, consolidated transfer to settle these balances.

Specifically:

1. Calculate the net balance for each bank.
2. Identify a single transfer that resolves all net balances. This transfer will be from a designated "Bank A" to other banks if their net balance is positive, or from other banks to "Bank A" if their net balance is negative.
   • If a bank's net balance is positive, a transfer occurs from Bank A to that bank for the netbalance amount.
   • If a bank's net balance is negative, a transfer occurs from that bank to Bank A for the absolute value (mod(netbalance)) of the netbalance.
