#include #include using namespace std; struct eggy { string name; double tw; int ks; } a[55]; int main() { int sb,b = 0; cin >> sb; for(int i = 1;i <= sb;i++){ cin>>a[i].name>>a[i].tw>>a[i].ks; } for(int i = 1; i <= sb;i++){ if(a[i].tw >= 37.5&&a[i].ks == 1){ cout<<a[i].name<<endl; b++; } } cout<<b; return 0; }
