Each person gets at least one apple. Otherwise, there are distributions like 10 and 0, which would make the number more than 126.

Thanks to the reminder from user 2, there should be the condition that "each person gets at least one apple".

I'm following a bat version:
@echo off ( echo ┌───┬───┬───┬───┬───┐ echo │ A │ B │ C │ D │ E │ )>result.txt setlocal enabledelayedexpansion for /l %%i in (1,1,6) do ( for /l %%j in (1,1,6) do ( for /l %%k in (1,1,6) do ( for /l %%l in (1,1,6) do ( for /l %%m in (6,-1,1) do ( set /a num=%%i+%%j+%%k+%%l+%%m if !num! equ 10 ( if !count! equ 0 (echo ┝━━━┿━━━┿━━━┿━━━┿━━━┥ ) else echo ├───┼───┼───┼───┼───┤ echo │ %%i │ %%j │ %%k │ %%l │ %%m │ )>>result.txt&set /a count+=1 ) ) ) ) ) ( echo └───┴───┴───┴───┴───┘ echo 5 people divide 10 apples ^(each person gets at least one^) there are %count% ways of distribution )>>result.txt start result.txt
Still add the thick lines, so as not to affect the appearance

Hundred schools of thought contending is a very good learning method, appreciate the two of you～～

It can be done recursively, but the efficiency will be very low.

I have to admit, the moderator's layout is so clear and well-structured that it's easy to understand at a glance. I feel ashamed.

But in terms of calculation speed, VBS is a bit better.

Probably because of this line "if !num! equ 10" that makes the program match automatically. .. If you want to increase the speed and don't know if there are other methods?

Just modify it so that the number of apples can be entered.

Then I also modified the batch script that can specify the number of apples. I tested with 15 apples, and the batch script was indeed very slow, and the layout would also have problems (although it can be dealt with, but the code would be more complicated and not very universal):
@echo off :begin cls set count=0 set input= set /p input= Please enter the number of apples (press Enter directly to exit): if not defined input exit if %input% lss 5 echo The number of apples is too small, please enter again&pause&goto begin set /a max=%input%-4 ( echo ┌───┬───┬───┬───┬───┐ echo │ A │ B │ C │ D │ E │ )>result.txt setlocal enabledelayedexpansion for /l %%i in (1,1,%max%) do ( for /l %%j in (1,1,%max%) do ( for /l %%k in (1,1,%max%) do ( for /l %%l in (1,1,%max%) do ( for /l %%m in (%max%,-1,1) do ( set /a num=%%i+%%j+%%k+%%l+%%m if !num! equ %input% ( if !count! equ 0 (echo ┝━━━┿━━━┿━━━┿━━━┿━━━┥ ) else echo ├───┼───┼───┼───┼───┤ echo │ %%i │ %%j │ %%k │ %%l │ %%m │ )>>result.txt&set /a count+=1 ) ) ) ) ) ( echo └───┴───┴───┴───┴───┘ echo There are %count% ways to divide %input% apples among 5 people (each person gets at least one) )>>result.txt start result.txt goto begin

This is actually a problem of the division method.
Teacher namejm and the previous几位 teachers used the method of nested collision testing, which will extremely waste resources and have extremely low efficiency when the modulus is relatively large. A more direct method is to use the IF statement to control the division rule and directly give the result according to the rule.
The following is a crude example:

Long time no see. I optimized the code a bit. Give it a thumbs up. Passers - by, please evaluate.

----------------
Went to the city today to participate in the computer skills competition, but the ranking was fixed again....郁闷...

Make sure to see clearly!

Although I can't understand it all, I admire it

I really envy, when will I be able to reach this level?

VBS indeed has inherent advantages... This is fully reflected in the code competition in this post.

The same "exhaustive collision test algorithm"

VBS's:
if a+b+c+d+e=ccur(i) then
is much faster than the batch processing's:
set /a num=%%i+%%j+%%k+%%l+%%m if !num! equ %input% (...)
to an astonishing degree....

Does VBS automatically optimize the algorithm during execution?

Its speed is almost comparable to the "segmentation method rule control" algorithm on floor 10.

The "function" on floor 10 is already the ultimate algorithm.. but the speed is comparable to the exhaustive method of VBS code...

It seems that batch processing is okay for saving some effort, but it's a bit incompetent when it comes to complex calculations....
