Explain what is the depth first search, and what is the difference between breadth-first, and depth-first search/2022

In a written paper with annotated screenshots, please thoroughly address the following problems:
 

1. Explain what is a breadth-first search.
2. Implement the informal algorithm ( pseudo code) of breadth first search. Provide the description of what the code does.
3. Implement the breadth first search algorithm in Lisp. Enter your function definition into a text file. Then load it into LISP.
4. Explain what is the depth first search, and what is the difference between breadth-first, and depth-first search.
