And one little modification i want to do on that.. Now it gives me all the words in both the candidate and reference and their counts.

But the output i look for is, i want to know only minimum count of candidate words among both candidate and reference..

for e.g if a word "the" appears 7 times in candidate and 2 times in reference. it should be able to get 2 as the min between two counts. like this for all the words in candidate alone..

please give me an idea how to do this. I will try
