find_intersection

The algorithm of find_intersection

The find_intersection method takes in two sets, first_method_set and
second_method_set, and finds their intersection using a recursive search algorithm.

Here is the process of find_intersection

1. Check that the input sets are not empty. 
    If one of the sets is empty, raise a ValueError.
  
2. Use the & operator to find the intersection of the two sets. 
    If the intersection is not empty, return the resulting set.
  
3. If the intersection is empty, call the method_recursive_search 
    function with the input sets and a specified maximum depth.
  
4. The method_recursive_search function recursively searches for 
    the intersection of the two input sets up to the specified depth 
    by splitting the sets into subsets and comparing each subset's elements. 
      - If the intersection is found, return the resulting set. 
      - Otherwise, return None.

The code of find_intersection

    def find_intersection(self, first_method_set, second_method_set, depth=1):
        """
        Find the first_method_list ∩ second_method_list.

        :param first_method_set: first list that contains each MethodAnalysis.
        :param second_method_set: second list that contains each MethodAnalysis.
        :param depth: maximum number of recursive search functions.
        :return: a set of first_method_list ∩ second_method_list or None.
        """
        # Check both lists are not null
        if not first_method_set or not second_method_set:
            raise ValueError("Set is Null")
        # find ∩
        result = first_method_set & second_method_set
        if result:
            return result
        else:
            return self.method_recursive_search(
                depth, first_method_set, second_method_set
            )

Welcome!
Could you update the alignment style of the algorithm description?
You can refer to the previous doc.
