The values in each row far exceed the maximum value that can be calculated by cmd.
Required, correct output, no temporary files are generated, and the code is efficient and common. Complete the question and add points based on your ideas.
Batman:
First, describe the following ideas:
This question is indeed a major challenge for us. Why? The main requirement is to sort all the large numbers in the text,
All values far exceed the maximum value that can be calculated by cmd. It is not feasible to use the conventional comparative method. This is one of the difficulties;
Second, these values are randomly generated and the total number of characters is not fixed, and may even exceed the length of several and dozens of lines. For example, the values are determined by character.
To ensure the maximum number of characters in the line, efficiency will be insurmountable obstacles to such a solution; the third main requirement is not to generate temporary text
To use findstr/o to obtain the maximum number of characters in a row.
The summary is as follows:
To use common code, you must obtain the maximum number of characters in a row. One method is to use the character-by-character method, which poses a big problem in efficiency;
The second method is to use findstr/o to get the character offset of each line at a time, and then obtain the maximum number of characters in the line through processing, which is more efficient
The character-by-character method is much higher, but because findstr/o alone cannot get the offset of unlineed characters in text lines, it must be imposed on unlineed lines.
Press enter to use a temporary file without damaging the original file.
When writing code, we generally follow four principles: high efficiency, general purpose, concise, and do not generate temporary files as much as possible.
One is efficiency, followed by general purpose. Simplicity and the absence of temporary files are not the main considerations.
The following two solutions are provided:
I. The versatility is almost the same (the numeric characters are in one line is absolutely no problem), high efficiency, concise code, no temporary files:
@ Echo off & setlocal enabledelayedexpansion
For/l % I in (1, 1, 80) do set "kong =! Kong! #"
For/f % I in (1.txt) do (
Set "str = % I % kong %"
Set "a =! Str :~, 80! "
Set "a =! A: % I =! "
Set "_! A! % I ="
)
For/f "delims = _" % I in ('set _ ') do (
Set "str = % I"
Echo! Str: # =!
)
Pause> nul
2. Extremely high versatility and efficiency. Temporary files are generated, and the code is complicated:
Copy codeThe Code is as follows: @ echo off & setlocal enabledelayedexpansion
Set "max = 0" & set "a = 0"
For/f % I in (1.txt) do echo % I> 2.txt
Echo.> 2.txt
For/f "tokens = 1, 2 * delims =:" % I in ('findstr/n/o. * 2.txt ') do (
Set/a n + = 1, m = n-1
Set "num = % I" & set "_! N! = % J "& set" # % I = % k"
If! M! Gtr 0 set/a = _! N! -_! M! -2
If! Max! Lss! A! Set "max =! A! "
)
Set/a num-= 1
For/l % I in (1,1, % max %) do set "kong =! Kong! #"
For/l % I in (1, 1, % num %) do (
Set "str =! # % I! % Kong %"
Set "a =! Str :~, % Max %! "
Call, set "a = % :! # % I! = %"
Set ".! A !! # % I! ="
