◆Binary System
How many digits are needed to write down all the numbers from 0 to 9999 in
binary system?
If the same question was asked for numbers from 0 to 5, the answer would be
12 (0, 1, 10, 11, 100, 101 --> a total of 12 digits).
用二進制表示0~9999 總共需要幾個數字?
如果問題改成0~5的話 答案是12.
(0, 1, 10, 11, 100, 101 --> 共12數字)
這題Difficulty rating 跟上一題反差應該會超大..
