Hi,
I have a data sample as shown below. I want to fill in the left column so that the line will be continuous. For example, between 1 and 5 should be 2,3,4. And corresponding values in the right column will be 0. Thus the expected data should look like that:

PERLCC(1) Perl Programmers Reference Guide PERLCC(1)
NAME
perlcc - generate executables from Perl programs
SYNOPSIS
$ perlcc hello # Compiles into executable 'a.out'
$ perlcc -o hello hello.pl # Compiles into executable 'hello'
$ perlcc -O file # Compiles using the optimised C backend
$ perlcc -B file # Compiles using the bytecode backend
$ perlcc -c file # Creates a C file, 'file.c'
$ perlcc -S -o hello file # Creates a C file, 'file.c',
# then compiles it to executable 'hello'
$ perlcc -c out.c file # Creates a C file, 'out.c' from 'file'
$ perlcc -e 'print q//' # Compiles a one-liner into 'a.out'
$ perlcc -c -e 'print q//' # Creates a C file 'a.out.c'
$ perlcc -I /foo hello # extra headers (notice the space after -I)
$ perlcc -L /foo hello # extra libraries (notice the space after -L)
$ perlcc -r hello # compiles 'hello' into 'a.out', runs 'a.out'.
$ perlcc -r hello a b c # compiles 'hello' into 'a.out', runs 'a.out'.
# with arguments 'a b c'
$ perlcc hello -log c # compiles 'hello' into 'a.out' logs compile
# log into 'c'.
DESCRIPTION
perlcc creates standalone executables from Perl programs, using the code generators provided by the B module. At present, you may either
create executable Perl bytecode, using the "-B" option, or generate and compile C files using the standard and 'optimised' C backends.
The code generated in this way is not guaranteed to work. The whole codegen suite ("perlcc" included) should be considered very experimen-
tal. Use for production purposes is strongly discouraged.
OPTIONS
-Llibrary directories
Adds the given directories to the library search path when C code is passed to your C compiler.
-Iinclude directories
Adds the given directories to the include file search path when C code is passed to your C compiler; when using the Perl bytecode
option, adds the given directories to Perl's include path.
-o output file name
Specifies the file name for the final compiled executable.
-c C file name
Create C code only; do not compile to a standalone binary.
-e perl code
Compile a one-liner, much the same as "perl -e '...'"
-S Do not delete generated C code after compilation.
-B Use the Perl bytecode code generator.
-O Use the 'optimised' C code generator. This is more experimental than everything else put together, and the code created is not guaran-
teed to compile in finite time and memory, or indeed, at all.
-v Increase verbosity of output; can be repeated for more verbose output.
-r Run the resulting compiled script after compiling it.
-log
Log the output of compiling to a file rather than to stdout.
