Collect, this needs to be combined with reality, not just understand by looking at it.

Well, let's see. The original text is "怎么说呢！
看过之后才知道自己的无知！". Translating it: "How should I put it!
Only after reading did I realize my own ignorance!"

In the line `set "p="&for /l %%a in (1 1 %1)do call set "p=%%p%%%~3"`, the `call set "p=%%p%%%~3"` part has the following function:
The `for /l` loop is iterating from 1 to the value of `%1`. For each iteration, it is using `call set` to concatenate the current value of `p` with the substring `%~3`. Specifically, `%~3` is taking the third command-line parameter (after removing any surrounding quotes), and in each iteration of the loop, it is appending that substring to the current value of `p`. So it's building up the string `p` by repeatedly appending the third parameter a number of times equal to the value of `%1`.

There is a sentence in the second code of building 15 that I don't understand:
set "p="&for /l %%a in (1 1 %1)do call set "p=%%p%%%~3"
Which expert can explain what the role of the following call set "p=%%p%%%~3" is?
It can be viewed separately: %%P%% (refer to the example program of the building owner above about delay) %~3 (represents the third parameter, the parameters are %1~%9, and %0 is the command line itself)
I don't know if my understanding is correct, please correct it in time

I like this kind of explanation, haha. It's easy to understand at a glance, and anyone who can read can learn it, haha.
