It seems that my expression ability is quite problematic.
Do it again
Require to generate a text file with content being a, b and spaces, but the total number of a and b is 60.
The first line cannot have spaces and must be interlaced like ababab, not like bba or aab.
For example:
Suppose the first randomly obtained letter is a, then write a into b.txt
Then obtain the second randomly obtained letter, suppose it is a again, then write it below the previously obtained a. If it is b, then write it in the first line of b.txt, that is, side by side with the first a.
Continue to obtain the randomly obtained letter, then judge whether it is the same as the previous letter. If it is the same, write it directly below the previous letter. Note: "is the previous letter", otherwise write it in the first line.
Then the final result obtained in this way will be the following format of text.

ababababa

a ab b ba

  ab b  a

   b    a

Let me state my train of thought~

abflag = "sloreissloreleeandsloreleeisslorehahailovedoscndosgood"

Randomly generate a number to represent the row~ For example, 12
Then generate
abababababab as the first row, ab = 12
Then start:
i = i + 1
If the i%12th character of abflag is " ", see whether it's odd or even and directly output a or b, ab += 1
i%2……
If odd, then a or " "……Random next
If it's " ", then replace the i-th character of abflag with " ", else that's a, oh right~ ab += 1
If even, then b or " "……Random again
If it's " ", then replace the i-th character of abflag with " ", else that's b, oh right~ ab += 1
Do I need to handle the line break for i%12 by myself?
Hmm, ab = 60啦~88

See if you can understand this pseudo-code~ If not, just treat it as a mark……
No interest in processing text with P~

By the way, let's comment on the crooked-headed～～thinking problem...

Randomly choose to start with a or b? x = a? b
Randomly a number of lines, such as 8

k = 60 - 8
Start the loop
Randomly generate a number i ≤ k (k = k - i)
Generate i consecutive x

Randomly generate a number i ≤ k (k = k - i)
Generate i consecutive reversed x (if x is a, then reversed x is b)

If the loop has reached the 7th time... output all remaining k...
If k = 0, end...

This will generate a 52-character within 8 lines...

Suppose starting with a...
The first random is 8

In the loop, the first generated is 9
Output
aaaaaaaaa
Then the loop generates 5
bbbbb
Then the loop generates 0

Then the loop generates 4
bbbb
Then the loop generates 8
aaaaaaaa
Then the loop generates 0

Then the loop generates 12
aaaaaaaaaaaa
7 loops and still not enough 60?
The remaining 14 are given to you
bbbbbbbbbbbbbb
Result:

aaaaaaaaa

bbbbb

aaaaaaaa



bbbb

aaaaaaaa



aaaaaaaaaaaa

bbbbbbbbbbbbbb

There are codes for row-column conversion in the forum, right?
Convert and input to b.txt
Then output:
babababa
type b.txt

This seems troublesome? I don't know which is faster...
If not converting, generating this code is the easiest...

I'll come one. This code will display that ECHO is off because the number of a and b is less than 60 (can only be closed by closing the window, sweat... Hope experts can improve it). Due to limited level, the number of characters in the first line is all even numbers (alas, sweat again...), of course, it can also be odd, just because it's too far-fetched, so it's not. There is no so-called algorithm, only a little idea, that is, compare the characters in the corresponding position of the next line with the previous line, if they are different, replace them with spaces. I hope experts can give a more efficient and concise code (preferably explain the algorithm so that novices and we chumps can learn).

for /l %%i in (1,1,%d%) do (

    ) else (

  ) else (

)

if %numa% gtr 60 (if %numb% gtr 60 echo %var2%&pause&exit /b)

if %n% lss %e% goto :more

goto :again

Oh my God! Finally there is someone who understands the problem. There are indeed bugs in the code, and it seems that b and a are not very random. What is required is that each a or b is randomly obtained. Not bad either, bonus for encouragement.

And b and a don't seem very random

set "code=ab"
set f=%random%%%2
call set g=%%code:~%f%,1%%
Is this not random?

Oh, that's right. It should be random. I just noticed that your result has so many letters at first. The total should be 60.

Your code doesn't seem to be in a fixed output format?
And md, rd =... Creating a folder is...

Floor 39 has the correct format, but at first glance, your number of columns can be customized? Then aren't a and b not random? If each a and b is random, then the number of columns cannot be predicted.

Your code doesn't seem to be in a fixed output format?
And md, rd =。= Creating folders is...

Because I can't control the number of output characters, when it exceeds the range, it will display "ECHO is off", so I can only create folders to determine whether the variable is a space (that is, if I can create a folder, then continue outputting, otherwise exit)

@echo off

Sweat!
I just feel that my code needs to run the loop tag about 30 times on average, which is not very efficient. I wanted to find a more efficient code, but I didn't expect that more than 40 posts came up, and most of them didn't understand the question. My expression ability is really extremely poor. I believe this post can no longer arouse the interest of other experts. Alas...
Still use code to illustrate the problem. In order to display beautifully, I replaced a and b with two other symbols, which looks clearer.
The code is as follows:

@echo off&color 1f

set _0=○&set "_1=●"&set /a ko=60

setlocal enabledelayedexpansion

for /l %%l in (1 1 %ko%) do (

   set /a w=!random!%%2

   call set "ss=%%_!w!%%"

   if not "!ss!"=="!flag!" (

      set "flag=!ss!"

      set /a h=1

      set "num1=!num1!!ss!"

      call :loop     

      ) else (

        set /a h+=1

        call set "num!h!=%%num!h!:~0,-1%%!ss!"

))

for /l %%l in (1 1 %ko%) do if not "!num%%l:　=!"=="" echo !num%%l!

echo.&pause&exit

:loop

   for /l %%l in (2 1 !ko!) do set "num%%l=!num%%l!　"

goto :eof

Then take a closer look...


Customization is nothing special... Because the random result may not be ideal...
If you get a 1!
Then there are 60 a's in one column...

Who told you that the problem is also strange...

The first line cannot have spaces and must be interleaved like ababab

Each a and b are random...

Did you random like this?
Your first line is the maximum number of columns...
Mine is like this...

If you don't modify the default slore, the number of columns and the maximum value are set randomly...

Except for the first line, the rest are all random...
