1. 泰勒發明一種方法來擴展一組數.例如將一組數[1,8]泰勒化,
則可造出兩組數[2,9]與[3,10],它們的每一項都由前組數的
每一項各加1而得,再將這三組數依序合併在一起而得另一組數[1,8,2,9,3,10].
若他由只有一個數[0]的這組數開始,不斷地將它泰勒化,則可得一組數:
[0,1,2,1,2,3,2,3,4,1,2,3,2,3,4,3,4,5,2,3,4,......]
請問這組數中的第2012個數是什麼?
答:009
2. 在我的計算器屏幕上,當所顯示的數為2659時,若我把計算器顛倒過來,
則屏幕上的數可讀成為6592.其中數字0,1,2,5,6,8,9,當把計算器
顛倒過來,屏幕上顯示的數可分別讀成0,1,2,5,9,8,6.從1開始,
第5個把計算器顛倒過來可讀的數為8,第15個為21.
請問第2007個把計算器顛倒過來可讀的數之末三位是什麼?
答:898

q1 英文好似寫得清楚一點。
Terry has invented a new way to extend lists of numbers. To Terryfy a list such as [1, 8] he creates two lists [2, 9] and [3, 10], where each term is one more than the corresponding term in the previous list, and then joins the three lists together to give [1, 8, 2, 9, 3, 10]. If he starts with a list containing one number [0] and repeatedly Terryfies it he creates the list.
[0, 1, 2, 1, 2, 3, 2, 3, 4, 1, 2, 3, 2, 3, 4, 3, 4, 5, 2, 3, 4...].
What is the 2012th number in this Terryfic list?
