The title is as follows: The existing array length is n+1, which contains 1 to n-2, the order is uncertain, of which two numbers appeared two times, now to find out the two digits. Example A={2, 3, 1, 4, 5, 2, 4}, this array length is 7, storing 1 to 5, but 2 and 4 appear two times, program output 2 and 4. Method 1 Brute Force search Main idea: For the number of I in the array, look for all the integers i+1 to the end, a number if it occurs two time

CTime are the same? As has been said before, CTime refers to the change of the inode. Now that we have changed the contents of the file, the Mtime has changed, so CTime will change. That is to say, as long as the mtime change, CTime will certainly change. How does that make ctime change and the rest of the same? We can do this by changing the permissions of the file, the user, the owning group, and so on. Here are some examples:Of course, since we can view the current atime, Mtime, and CTime, i
