[]AS3 algorithm instance] Output 1 to the maximum number of n digits title: input number n, sequentially output from 1 the largest n bits 10 binary number. For example, input 3, the output 1, 2, 31 until the maximum 3 digits is 999. 】

Idea: If we were to fill 0 in front of the number , we would find that the N-bit all 10 binary number is actually N from 0 to 9 of the full array. That is to say, we arrange each digit of the number from 0 to 9, and we get all the 10 binary numbers.
