Not a question. You need to provide code you have tried and ask a specific question to point out where you are stuck.

And? What is your problem? Where are you stuck?
This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.

Since I read both your question you need to create a simple hash function so you can do integer searches

Please don't think we can read minds or do astral projections to see your monitor. If you need help, the least you could do is to add some relevant code to your question or to explain your problem in such a way, that the users of CP can understand it. Otherwise, nobody will be able to help you.
what have you tried?[^]

According to Mathlab´s comment you can try to read all 5 text files to a hashtable/dictionary. Read them line by line, split each line into key and value and add them to the dictionary. The keys value has to be a list, because there may be more salesfigures for a city. Then write the dictionary to a text file.
