Description有一个球形空间产生器能够在nn维空间中产生一个坚硬的球体。现在，你被困在了这个nn维球体中，你只知道球面上n+1n+1个点的坐标，你需要以最快的速度确定这个nn维球体的球心坐标，以便于摧毁这个球形空间产生器。Input第一行是一个整数n(1=N=10)n(1。接下来的n+1n+1行，每行有nn个实数，表示球面上一点的nn维坐标。每一个实数精确到小数点后66位，且其

Winter has come, but at the Ural State University heating is not turned on yet. There’s one little problem: the University is heated only if all of the valves are opened. There are some technicians at
