C++ 풀이

#include <iostream>
#include <exception>
#include <string>
#include <stdexcept>
#include <vector>
#include <cmath>
using namespace std;

class Server {

	static int load;

			throw std::invalid_argument("A is negative");
		}
		vector<int> v(A, 0);
		int real = -1, cmplx = sqrt(-1);
		if (B == 0) throw 0;
		real = (A / B) * real;
		int ans = v.at(B);
		return real + A - B * ans;
	}

int main() {
	int T; cin >> T;
	while (T--) {
		long long A, B;
