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. 1 /**2 *ch Storing numbers3 *n n Number of digits4 *index Count Value5

How many times are the loops?Time limit:3000/1000 MS (java/others) Memory limit:65536/32768 K (java/others) total submission (s): 3096 Accepted Submission (s): 1144Problem Description we know that in programming, we often need to take into account the complexity of time, especially for the loop part. For example, if a for (i=1;iInput has T group case,tOutput for each case, outputs a value that represents the total amount of computation, perhaps a large number, then you only need to output the re

I had nothing to worry about refreshing Weibo. I accidentally saw an interview question and shared it with you. The question is, let you construct a function f (n) so that F (f (N) =-n. I started to think about it for a long time. After thinking about it for a long time, I actually wanted to recursive it. In fact, I listened to a simple question and used a base
