問題：A - Train #include <iostream> using namespace std; int main(void) { int n, i; cin.tie(0); ios::sync_with_stdio(false); cin >> n >> i; cout << n - i + 1 << "\n"; return 0; }</iostream>

問題：B - 105 #include <iostream> using namespace std; #define FOR(i, a, b) for (int i = (a); i < (b); ++i) bool getJudge(int x_n) { int cnt = 0; FOR(i, 1, x_n + 1) { if (x_n % i == 0) { cnt++; } } return cnt == 8; } int main(void) { int n, ans = 0;</iostream>…
