What i meant in the last statement is. I want to compare the keys at two hashes. let me be specific.

The whole program splits a sentence and compares each words of the sentence with two sentence i.e($str1,$str2).

What i needed is: for eg. if "the" word occurs in $str1 two times and $str2 one time. i want find the minimum value i.e is 1.

Same procedure for all the words in the sentence. The end output should give me the Word string and Its minimum count(after comparing counts in $str1 & $str2)..
