Backtracking Approach for Generating Subsets

  1. Define a helper function backtrack(start, path) that takes the starting index and the current subset path as arguments.
  2. If start equals the length of the input array, add a copy of path to the result list, as it represents a complete subset.
  3. Iterate over the array starting from start index to the end of the array.
  4. For each element at index i, add it to the path.
  5. Recursively call backtrack(i + 1, path) to continue building the subset.
  6. Backtrack by removing the last element added to path.
  7. After the loop, return the result list containing all subsets.
