1 題目如下：（ http://www.javaeye.com/topic/226364?page=1）
給你10分鐘時(shí)間，根據(jù)上排給出十個(gè)數(shù)，在其下排填出對(duì)應(yīng)的十個(gè)數(shù)
要求下排每個(gè)數(shù)都是先前上排那十個(gè)數(shù)在下排出現(xiàn)的次數(shù)。
上排的十個(gè)數(shù)如下：
【0，1，2，3，4，5，6，7，8，9】
小提示：下排的10個(gè)數(shù)之和正好是10

只是不知道是否唯一？
2 有十二個(gè)乒乓球特征相同，其中只有一個(gè)重量異常，現(xiàn)在要求用一部沒(méi)有砝碼的天平稱(chēng)三次，將那個(gè)重量異常的球找出來(lái)。
答案： 一個(gè)很酷的JS寫(xiě)的解法
