時限:2009/12/31(四)19:00~2010/1/5(二)18:59
答案可上傳5次,但每改1次扣20分(基本分為100分)
在比賽期間內可隨時回答,但只有在時限內回答者有額外加分
◆Coins Triangles
12枚硬幣被排成如圖所示(圖:http://www.puzzleup.com/2009/img/puzzle/2009/24.jpg )
這些硬幣的中心點形成不同的正三角形(如AEF, BJL, DGM等),你的工作就是移走最少數目
的硬幣,使得沒有這樣的正三角形繼續存在,你該移除哪幾枚硬幣?
按照英文字母的順序,輸入這些硬幣的字母當作答案,但字母間不可有空格(space)
假如你的解答不止一種,輸入字母排序較前的解答。
(這句我的理解是,假若解答有2個,分別為CEHJ跟BGLM,則輸入BGLM。)
