X is a good number if after rotating each digit individually by 180 degrees, we get a valid number that is different from X. Each digit must be rotated-we cannot choose to leave it alone. A number is valid if each digit remains a digit after rotation. 0, 1, and 8 rotate to themselves; 2 and 5 rotate to each other; 6 and 9 rotate to each other, and the rest of the numbers do not rotate to any other number and become invalid. Now given a positive number N, how many numbers X from 1 to n are good?

X is a good number if after rotating each digit individually by the degrees, we get a valid number that's different from X. A number is valid if each digit remains A digit after rotation. 0, 1, and 8 rotate to themselves; 2 and 5 rotate to all other;

Recently, I checked the running status of the WSUS server and found that two computers are still in the "not reported" status. Because these two computers are far away from each other, therefore, the information cannot be seen from the log file, and the log on the WSUS server is too complex, so it gives up. However, this problem also occurs on a computer in my house two days ago. So I checked windowsupdate. log in the windows directory and found the following error during update Detection: Date

, where the "Netstat-ano" parameter represents a digital display of all active TCP connections and TCP, UDP ports on which the computer is listening and displays the corresponding process ID PID number; "Findstr 1140" indicates a TCP connection that finds a process pid of "1140" and a TCP, UDP port listening condition (in practical applications, you need to replace the PID number you just noted or copied here for 1140).

Modify the resolution of Linux text (command line) mode In my system text mode, the default resolution is 800*600. when I use lynx to browse the webpage, I feel that the font is too large. if I want to adjust the resolution in this mode, I will go to google, the discovery is actually very simple. Go to the/boot/grub/directory, and you will see a file named menu. lst in it. use vim to open it and you will see the following content: # Grub. conf generated by anaconda## Note that you do not have to

If no prompt is returned at this time, it means that the process has not enabled any ports. 2. Check the process by port number Enter the "netstat-ano" command in the Command Pro
