Getting Unique Elements through Hash

[kimskams80]

Hi Gurus,

I have an array where each element is like this

Text Value

and I can easily use HASH to get unique set of elements. But hash what hash does is that it TREATS Letter's case into account too. Like if I have an element

Factory 1

and other

factory 1

then they will be stored in diff locations in Hash but I want that they should be stored on one place.

This is the code that i use

 my %hash   = map { $_, 1 } @BA;

Thanks

I dont wana use function "lc" of some other bz i want to keep the elements as they are .. but just dont want a case sensitive entry in hash

[Sixtease]

my %hash = map { lc($_), $_ } @BA;

Then simply get the unique list as values %hash instead of keys %hash
