$开什么数组，$

暴力出奇迹，打表过样例!

#include <iostream>
#include <iomanip>
using namespace std;
int main() {
	int a,b,c,d,e,f,g,h,i,j;
	cin >> a >> b >> c >> d >> e >> f >> g >> h >> i >> j;
	double ans = a * 28.9 + b * 32.7 + c * 45.6 + d * 78 + e * 35 + f * 86.2 + g * 27.8 + h * 43 + i * 56 + j * 65;
	cout << fixed << setprecision(1) << ans << endl;
	return 0;
}
