 ## Program Requirements & Submission Details
-In this assignment, you are required to use std::map, and std::set, you are NOT allowed to use any data structures we have not learned so far, but feel free to use data structures we have already learned, such as std::string, std::vector, std::list. In addition, **the web crawler component of your program must be recursive**.

+In this assignment, you are required to use std::map, or std::set. You are recommended to use both. You are NOT allowed to use any data structures we have not learned so far, but feel free to use data structures we have already learned, such as std::string, std::vector, std::list. In addition, **the web crawler component of your program must be recursive**.
 
 Use good coding style when you design and implement your program. Organize your program into functions:
 don’t put all the code in main! Be sure to read the [Homework Policies](https://www.cs.rpi.edu/academics/courses/fall23/csci1200/homework_policies.php) as you put the finishing touches on your solution. Be sure to make up new test cases to fully debug your program and don’t forget
