Hi all,

My aim is to write a program that will display the parent-child data in an array. I have an input file called 1.txt. This file contain data such as 10,20,30,40 Foreach data, read from the input file append by .txt to get the sub file data for the next...

The relation is as follows: 

1 -> 10, 20, 30, 40
10 -> 100, 101, 102
100 -> no data
101 -> 1011
1011 -> no data
102 -> no data

20 -> no data

30 -> 301, 302
301 -> no data
302 -> no data

40 -> 401, 402
401 -> 4011
4011 -> 40111
40111 -> no data
402 -> no data

(1,10,20,30,40,100,101,102,1011,301,302,401,402,4011,40111 .. are .txt files)

Need to start reading from 1.txt file and the resultant data from that should read subsequent files, finally all data should be stored in an array.

My program works having some problem to store all data... Could anyone please help me to solve this?

My code is given below: 

#!/usr/bin/perl

@ini_array = ();
#input file 
open(F,"C:/test/1.txt") or die "Can't open 1.txt file";
while(<F>) {
    chomp;
    push(@ini_array,$_);
}
close F;


@final_array;
foreach $ab (@ini_array) {
    push(@final_array,$ab);
    &common($ab);
}


sub common() {
    $fl = shift;
    open(A,"C:/test/$fl.txt") or die "Can't open $fl";
        @sublist = <A>;
    close A;

    $cnt = scalar @sublist;
    if ($cnt > 0) {
        subfl(\@sublist);
    }
    else {
        push(@final_array,@sublist);
    }

}


sub subfl() {
    $arfirst = shift;
    @ini_array1 = @$arfirst;
    foreach $ab1 (@ini_array1) {
        chomp($ab1);
        push(@final_array,$ab1);
        &common($ab1);
    }
}
