◆ONE AND TWO
You will generate a number using only the digits 1 and 2. Our condition
is that no sequence of 3 or more digits repeats more than two times.
What is the largest number satisfying this condition?
Example: If the number is “ABCDE…”,
Three-digit sequences are: “ABC”, “BCD”, “CDE”, …

問滿足此條件的最大數字為?
例:如果數字為 "ABCDE..."
三位數字序列有:"ABC", "BCD", "CDE", ...
四位數字序列有:"ABCD", "BCDE", ...
譯註:題目完全不同了呢
