Simple Bank System (Withdraw/Deposit/Transfer)

Problem: Simple Bank System (Withdraw/Deposit/Transfer) You are given an array balance of length n where balance[i] is the balance of account i+1 (accounts are 1-indexed). Process a sequence of operations: withdraw(account, money) deposit(account, money) transfer(account1, account2, money) Validation Any account id must be within [1, n], otherwise the operation fails. withdraw: fails if balance[account-1] < money. transfer: fails if balance[account1-1] < money. deposit: no balance constraint. Output A common OA variant: process operations in order; if any operation fails, output -1. Otherwise output the final balances. Suggested input format Line 1: integer n Line 2: n integers balance Line 3: integer q Next q lines: withdraw a x, deposit a x, or transfer a b x Constraints 1 <= n, q <= 2 * 10^5 0 <= balance[i], money <= 10^9 Example Input 3 10 5 20 3 withdraw 2 3 deposit 3 10 transfer 1 3 5 Output 5 2 35
