Question

python

Function Name: find_me Parameters: a dictionary of strings mapping to strings ( dict ), person1 ( str), person2 (str) Returns: number of people in between the first and last person ( int ) Description: Given a dictionary and two names, find the number of people in between them. The dictionary maps a person ( key ) to the person ( value ) in front of them in a line. If person2 is the value of the personi key, then they have 0 people in between them. If there is no path between the two people, return None. Hint: A while loop to check if the current person you are on is actually in the dictionary might be helpful. However, this also can be done with a for loop. You pick!

Answer 1

def find_me(people, person1, person2):
    if person1 == person2:
        return 0
    else:
        count = 0
        if person1 not in people:
            return None
        while people[person1] != person2:
            person1 = people[person1]
            if person1 not in people:
                return None
            count += 1
        return count


# Testing the function here. ignore/remove the code below if not required
people = {"Damian": "Jakob", "Rajit": "Jasmine Y.", "Jasmine Y.": "Arvin", "Caitlin": "Cathy", "Jakob": "Caitlin"}
person1 = "Damian"
person2 = "Cathy"
print(find_me(people, person1, person2))

people = {"Arushi": "Juliette", "Brae": "Arushi", "Anthony": "Jasmine C."}
person1 = "Brae"
person2 = "Jasmine C."
print(find_me(people, person1, person2))
