Strengths:

  • Good use of backtracking pattern in both solutions.
  • Clean code structure and good variable naming.
  • Correct implementation of the palindrome partitioning problem.

Areas for Improvement:

  • For the subsets problem, you need to add the current subset to the result at each step of the recursion, not just at the base case. The reference solution shows this by adding the path when i == nums.size().
  • In the subsets problem, you're currently only printing the subsets rather than collecting them in the result list.
  • Consider adding comments to explain the backtracking logic, especially for more complex problems.

For the subsets problem, you could modify your solution like this:

def subsets(self, nums: List[int]) -> List[List[int]]:
    res = []
    n = len(nums)
    def backtrack(i, sofar):
        res.append(sofar.copy())  # Add current subset
        for j in range(i, n):
            sofar.append(nums[j])
            backtrack(j+1, sofar)
            sofar.pop()
    backtrack(0, [])
    return res
