出自某高智商博客，猜想版上大約有定期在逛那兒的強者已經看過了，請多包涵
問題是：怎麼用圓鋪滿三維空間，而不重複且不遺漏
(這裡的鋪滿相當於建構一系列圓，使得空間裡的每個點恰位於某個圓上)
Hint
原解非常抽像，幸好回覆原博文的版眾補了一個類似引理的東西我總算才看懂
這個引理／提示本身又是一個謎題，解決後原題大概就OK了 當然要挑戰從頭想起
也是可以的。
<欲看請開燈> 已知球面或平面是無法用圓無遺漏無重複的填滿的，然而只要
在其上挖掉兩個點，剩下的部分必可以被填滿。請驗證挖掉的不必是球面的
對蹠點，而可以是任意兩點。 ^^^^^^^^^^^^^^^^^
^^^^^^^^^^^^^^^^^^^^^^^^^
