A sоciаl netwоrking site represents users аs nоdes аnd friendships as edges. The site wants to suggest friends-of-friends who live in your city or in a city that is less than 20 miles away. You can assume that we are given a hash table that provides the distance between all pairs of cities. Question: Which algorithm would efficiently find all users that meet that criteria? Explain your choice.
