    @ShadowZzz You can write your answer in pseudo code.

    Definitely many ways to do this. A few come to mind. I'll use Python as the example language. 1. Append each entry to the list then run a list.count() command on each entry. (Of course you'd have to account for the multiple entries, maybe by sorting the list and only printing if the current entry is not the same as the one before it.) 2. Create a dictionary. If the entry does not exist in the dictionary, add it with the value of 0. If the entry does exist, increase the associated value by 1. 3. Variables. You could sort your list, and then create a "num_frequency" variable. Increment your variable by 1 when your list entries are duplicates. Display the variable and reset it when they aren't. Of course, not all approaches are equal. But this at least shows a number of ways to approach the problem.
