Hello everyone
I would like to sort an array so that it does not contain any values
twice or three times.
Unfortunately, perldoc -q sort does not help me very much.
Here is an example of this array :
@array = ('smith ', 'john ', 'edward ', 'smith ', 'edward ', 'john ');
I would like to have : @array1 = ('smith ', 'john ', 'edward ');
Thanks in advance for your help and especially your explanations.
