- Write a C++ program to read three synonym files (F1, F2, F3) in parallel threads (one per file), merge all synonyms, remove duplicates, and output groups of connected words. Each group should be printed once, with words sorted alphabetically (lowercase) and an option for ascending/descending sort.
- How would you implement DFS on a graph, both recursively and iteratively?
- Describe the Consumer-Producer problem. How can it be solved using mutex and semaphore? What are the potential issues with accessing shared memory?
