Can anyone help. I have to write two programs, one in C# and one in Java Script, to complete the same outcome.

My main/first issue is that I am not too sure how to write a function using Visual Studio Code that takes a file as an input from the command line prompt.

Given a text file and an integer k, you are to print the words (and their frequencies of occurrence) whose frequencies of occurrence are the k largest (upper limit) in order of decreasing frequency; breaking any ties in increasing words alphabetical order. Words are consecutive sequences of ASCII alphabetical letters (A-Za-z), where letter case is ignored, and all other characters are ignored.
