Правила банковского счёта

Encapsulation keeps an object's data private and only changes it through methods that enforce the rules. Баланс банковского счёта может изменяться только через deposit and withdraw.

Start with a balance of 0 and process the operations, each deposit <amount> or withdraw <amount>:

• An amount that is 0 or negative is rejected.
• A withdrawal larger than the current balance is rejected.
• Otherwise the balance changes.

Implement bank_account_rules(operations).

Input

operations: Операции в заданном порядке.

Output

Return [final_balance, rejected_count].

Ограничения

0 ≤ число операций ≤ 100,000

−10^9 ≤ сумма ≤ 10^9

Примеры

Ввод:
operations = ["deposit 100", "withdraw 30", "withdraw 200"]

Ожидаемый вывод:
expected = [70, 1]

Ввод:
std::vector<std::string> operations = {"deposit 100", "withdraw 30", "withdraw 200"};

Ожидаемый вывод:
std::vector<long long> expected = {70, 1};

Ввод:
string[] operations = new string[] {"deposit 100", "withdraw 30", "withdraw 200"};

Ожидаемый вывод:
long[] expected = new long[] {70, 1};

Ввод:
operations = ["deposit -5", "withdraw 0", "deposit 10"]

Ожидаемый вывод:
expected = [10, 2]

Ввод:
std::vector<std::string> operations = {"deposit -5", "withdraw 0", "deposit 10"};

Ожидаемый вывод:
std::vector<long long> expected = {10, 2};

Ввод:
string[] operations = new string[] {"deposit -5", "withdraw 0", "deposit 10"};

Ожидаемый вывод:
long[] expected = new long[] {10, 2};
