Hello Master's

Stuck at a particular logic to count total number of occurrence of a string stored in hash values. Then LOOP to print few lines of statement, also replace corresponding hash key in print statement. I don't know how to print hash keys in print statement.

All the above need to print to a file, that's opened before LOOP

Any ideas will be helpful. Thank you.
