Input

Line 1: owner. Line 2: n. Then n lines dep X / wd X.

Output

Any rejected lines, then the summary.

Example

Input

ann
5
dep 100
wd 30.5
wd 500
dep -5
dep 10

Output

rejected
rejected
ann: 79.50

Hints

The member initializer list : owner_(owner) sets fields before the constructor body runs.

Solution explanation

explicit stops accidental conversions like Account a = "ann";.

#include <iostream>
#include <iomanip>
#include <string>
using namespace std;

class Account {
public:
    explicit Account(string owner) : owner_(owner) {}

    bool deposit(double amount) {
        if (amount <= 0) return false;
        balance_ += amount;
        return true;
    }

    bool withdraw(double amount) {
        if (amount <= 0 || amount > balance_) return false;
        balance_ -= amount;
        return true;
    }

    const string &owner() const { return owner_; }
    double balance() const { return balance_; }

private:
    string owner_;
    double balance_ = 0;
};

int main() {
    string owner;
    int n;
    cin >> owner >> n;
    Account acc(owner);
    for (int i = 0; i < n; i++) {
        string cmd;
        double amount;
        cin >> cmd >> amount;
        bool ok = cmd == "dep" ? acc.deposit(amount) : acc.withdraw(amount);
        if (!ok) cout << "rejected\n";
    }
    cout << fixed << setprecision(2) << acc.owner() << ": " << acc.balance() << "\n";
    return 0;
}
