1. ignore 1st and 2nd line
2. Take colum one and compare the row 3 and 4 it should be equal
3. Take colum two and comapre the row 3 and 4 it should be equal
4. then check colum 4 and check row 3 and 4 greater value, if found the greater value check with the next row and print greater value of the same group.


The code i had tried for it is
#!/usr/bin/perl
#use strict;
use warnings;

open FILE,"out07.txt";

my @fields = split / /, <FILE>;
chomp @fields;
my @lines = split (/(\n)/, "@fields");
for (@lines)
{
    print @fields,"\n";
    
}
