TLDR: The program to write must calculate words frequency from a given file.
We will provide you a file with some text on it, and you have to open it and find the frequencies of all words in it having the following requirements:
- Assume a valid UTF-8 input file
- All words must be processed in lower case (ignore case) Output must be sorted by word alphabetically
- Output must have one entry per word, having its frequency next to it
