"感度3000倍問題"を解いてみた

twitterで見かけたこの問題が、競技プログラミング的(AtCoderの300点問題くらい)だと感じたのでc++で解いてみた。


using namespace std;

int main(int argc, char *argv[])
{
	//init
	string orc = "ABCDE";
	sort(orc.begin(), orc.end());

	//calc
	while (next_permutation(orc.begin(), orc.end())){
		int kando = 0;
		for (size_t i = 0; i < orc.length(); i++){
			char drug = orc[i];
			switch (drug){
			case 'A':
				kando /= 2;
				break;

			case 'B':
				kando -= 900;
				break;

			case 'C':
				kando += 2000;
				break;

			case 'D':
				kando *= 5;
				break;

			case 'E':
				kando += 500;
				break;

			}
		}

		if (kando == 3000){
			cout << orc << endl;
		}
	}

	return 0;
}
