bugfree Icon

Hello, I am bugfree Assistant. Feel free to ask me for any question related to this problem

Requirements Clarification & Assessment

  1. Understanding the Problem:

    • The problem involves determining the degrees of separation between any two actors, which is essentially finding the shortest path in a graph where actors are nodes and connections via movies are edges.
  2. Defining the "Connection":

    • A connection can be defined as two actors appearing in the same movie. This needs to be clearly defined to ensure consistency in the approach.
  3. Data Requirements:

    • Access to a comprehensive dataset of movies and actors, such as IMDb, which includes information about which actors have appeared in which movies.
  4. Scope of the Problem:

    • Determine if the solution should handle a few actor pairs or if it needs to be scalable for a large number of queries.
  5. Performance Considerations:

    • Assess the computational complexity and performance requirements, especially if dealing with a large dataset.
  6. Technology Constraints:

    • Identify any constraints related to the technology stack that must be used, such as specific database systems or programming languages.
