Backtracking

A backtracking algorithm is a problem-solving algorithm that uses a brute force approach for finding the desired output.

• 1.2) Subsets
  Given a set of distinct integers nums, return all possible subsets (the power set) of the set.
• 1.1) What is Backtracking?
  Backtracking is a problem-solving technique that involves exploring all possible solutions to find the correct one. It is often used when dealing with problems that have multiple potential solutions, and the goal is to find one or more solutions that satisfy certain constraints or conditions.
