Hello

My query is quite different but still am sure it can be done with Perl although i don't know how

I have an array of all the bigrams that exist in the alphabet. A bigram is a two - letter combination.

I have all the bigram combinations in an array so $bigram[0] is aa and $bigram[675] is zz. 

 
$bigram[0] = "aa"; $bigram[1] = "ab"; ...$bigram[675] = "zz"

Now i have an array that contains a bigram for every element. From that array i want to check which bigrams from my list exist in my @bigram_list array. For those bigrams that indeed exist once or more i want to make another array the same size as my @bigram array that will have a 1 for those bigrams that exist and a 0 for the bigrams that don't exist in my @bigram_list array.

For example:

@bigrams : as said previously 

 
@bigram_list = ("ac","ab","wd","xs");

So here, the new array that i want to hold the numbers will have 0 in every element apart from the positions where "ac", "ab", "wd" and "xs" are where there should be a 1.

Sorry, if this is complicated i tried to make it as understandable as i could. Does anyone know of a way i could do this? Thanks for looking
