Don't use double, use Int64 only

this part of code get WA10
    __int64 ans = 0,
        sum_all_x = accumulate( vx.begin(), vx.end(), 0 ),
        sum_all_y = accumulate( vy.begin(), vy.end(), 0 );

but this part of code get AC
    __int64 ans = 0,
        sum_all_x = accumulate( vx.begin(), vx.end(), 0i64 ),
        sum_all_y = accumulate( vy.begin(), vy.end(), 0i64 );
