Re^2: finding matches in the same array

This gives more weight to the last number (if there are more than 2):

my @sequence = ('acgt','actg','cggt','cggt', 'actg', 'actg');
my @numbers = ('1234','2345','3244','3455', '5230', '100000' );

gives 51893.75 when it should be 34526.3333333333

You are right, it's utterly different algorithm. The correct one is as follows: `@seq = ('acgt','actg','cggt','cggt', 'actg', 'actg'); @num = ('1234','2345','3244','3455', '5230', '100000' ); for( 0..$#seq ){ $struct{$seq[$_]}->[0] += $num[$_] and $struct{$seq[$_]}->[1]++ } for( keys %struct ){ print "$_\t", $struct{$_}->[0] / $struct{$_}->[1], $/ } __END__ STDOUT: acgt 1234 cggt 3349.5 actg 35858.3333333333` [download]	[reply] [d/l]

@seq = ('acgt','actg','cggt','cggt', 'actg', 'actg');
@num = ('1234','2345','3244','3455', '5230', '100000' );

for( 0..$#seq ){
   $struct{$seq[$_]}->[0] += $num[$_]
   and
   $struct{$seq[$_]}->[1]++
}

for( keys %struct ){
  print "$_\t", $struct{$_}->[0] / $struct{$_}->[1], $/
}

__END__

STDOUT:

acgt    1234
cggt    3349.5
actg    35858.3333333333
