I need a C program that can be compiled in linux that reads two input .txt files and identifies all unique common words that appear in both .txt files and write them into an output file in ascending sorted order based on the word field using the strcmp() function. You can only use the linked list data structure in this project but you are free to use singly or doubly linked lists. Thanks! (You are not allowed to use qsort function). I will upvote when completed!
