Hi to all the monks I have two arrays and each element is a string. Each string might exist more than once in each array. What i want is the number of elements that exist in both arrays. The problem is that if a string exists more than once in each array only add the smallest number. So if i have a string in one array twice and in the other one 5 times then add 2. I tried something but without being able to fix this problem, if i had the example before it would add 5. 
%string_1 = map{$_ =>1} @string1;

@intersection_of_the_2_arrays = grep( $string_1{$_}, @string2 );
    
$number_of_similar_words = scalar(@intersection_of_the_2_arrays);

Thanks for viewing and for anyone who can help.
