2번 문제 int main() { int n, s; scanf("%d", &n); for(int i=1; i<=n; i++) { if(i%2==0) { s += i; }      } printf("%d", s); }

1. 문제 int main() { int n, s; scanf("%d", &n); for(int i=1; i<=n; i++) { s += i; } printf("%d", s); }

if(n % 7 != 0) answer = n/7+1; else answer = n/7;

if(numbers[i]*numbers[j] > answer) { answer = numbers[i] * numbers[j];
