問題：B - Common Raccoon vs Monster #include <iostream> using namespace std; #define REP(i, n) for (int i = 0; i < (n); ++i) int main(void) { int h, n, a; cin.tie(0); ios::sync_with_stdio(false); cin >> h >> n; REP(i, n) { cin >> a; h -= a; } cout <</iostream>…

問題：A - Serval vs Monster #include <iostream> using namespace std; int main(void) { int h, a; cin.tie(0); ios::sync_with_stdio(false); cin >> h >> a; cout << (h % a == 0? h / a : h / a + 1) << "\n"; return 0; }</iostream>
