풀이 방법

<코드>

#include<iostream>
#include<cstring>
using namespace std;

int main(int argc, char** argv)
{
	int test_case;
	int T;
	cin >> T;

	for (test_case = 1; test_case <= T; ++test_case)
	{
		int command{ 0 };
		std::cin >> command;

		int commandType{ 0 };
		int value{ 0 };

		int currentVecocity{ 0 };
		int distance{ 0 };

		for (int i = 0; i < command; i++)
		{
			std::cin >> commandType;
			if (commandType != 0)
				std::cin >> value;

			switch (commandType)
			{
			case 0:
				break;
			case 1:
					currentVecocity += value;
				break;
			case 2:
				if (currentVecocity - value < 0)
					currentVecocity = 0;
				else
					currentVecocity -= value;
				break;
			}

			distance += currentVecocity;
		}

		std::cout << "#" << test_case << " " << distance << "\n";
	}

	return 0;//정상종료시 반드시 0을 리턴해야합니다.
