I have two files namely ICD-Codes-text which is tab format and other file named female.txt which has been split word by word . i need to compare the contents of female1.txt to ICD-codes file 0th array values. If there is a match then the matched value in female1.txt should be replaced with ICD-code files corresponding 1st array value. I am a beginner in PERL. I tried to write some code but i do not know where am going wrong or its completely wrong. Help me with this please

#!/usr/bin/perl

print "reading 'ansvarig_vardenhet_utf8.txt'\n";
open(WIN, "icd-10-codes.txt");
while($line = <WIN>) {
  @columns = split(/\t/, $line);
  #print "$columns[1]"; 
  foreach my $value (@columns) {
    #print "$value\n"
}
}
close(WIN);

print "reading 'ansvarig_vardenhet_utf8.txt'\n";
open(IN, "female1.txt");
while($line = <IN>) {
  %col = split(/ /, $line);
  #print "$columns[1]\n"; 
  foreach my $val (%col) {
      if($val == $columns[0]){
         $val =~ s/$val/$columns[1]/g;
         print IN ">>$val\n";
        }
      }   
}
close(IN);
