Can Brother youxi01 talk about the simple implementation principles and ideas? This is convenient for learning and can better understand and read the code~:)

Brother redtek, when I run the code on the 15th floor you posted, it always flashes by in an instant. I don't know why. So depressed...

Hehe……
It always flashes by because you saved it with Notepad (probably to the desktop).
There is no "pause" in the batch code to wait for you to press any key before exiting, so when you double-click the batch file with the mouse, it runs and exits automatically, closing the CMD Shell window: )
First enter the CMD Shell command window, then type...BAt in it and run: )

Re lxmxn 『Post 23』:

　　Brother NaiWaiHe's code in 7F also has similar issues. The problem lies in the two lines "if %%j GTR !l! set l=%%j & set m=%%i" and "if !.%1! GTR !maxN! set maxN=!.%1! && set max=.%1". The same problem occurs: there is an extra space before & and &&. Removing this space will fix it.

Changing the line "set . & goto :eof" on floor 15 to "set . &pause& goto :eof" will do it.

The simplest one ^_^

@echo off

setlocal EnableDelayedExpansion

set str=adadfdfseffserfefsefseetsdgadadfdfseffserfefsefseetsdga



:loop

set str$=%str$% %str:~0,1%&set str=%str:~1%

if not "%str%" == "" goto loop



for %%n in (%str$%) do (

  set /a .%%n+=1

if !.%%n! GTR !maxN! set maxN=!.%%n!&&set max=%%n)

set .

echo The most frequent occurrence: %max%=%maxN%

pause

exit

It's indeed the case. What I modified in 18th floor is also like this. Generally, it is suggested that there should be no spaces in the best way of connecting with &, &&

It seems that format specification is very important.

If the value of %1 is greater than the value of maxN, then set maxN to the value of %1 and set max to %1.

Thank you everyone,

As a new user, I really want to see such good code. It's enough for me to study.

It's really helpful...

I just want to ask the moderator if there can be more such activities in the future, so as to give us new users a good opportunity to study?

On behalf of new users, I say thank you to everyone
