LeetCode 40: Combination Sum Ii — Step-by-Step Visual Trace

1. 1Read the problem statement carefully to understand the constraints and requirements
2. 2Choose a suitable algorithm such as backtracking to solve the problem
3. 3Initialize an empty list to store the result and define a helper function to perform the backtracking
4. 4Sort the candidates array to handle duplicates and ensure unique combinations
5. 5Apply the backtracking algorithm to find all unique combinations that sum up to the target value

This solution benefits software engineers and developers who work on algorithmic problems and need to optimize their code for combinations and permutations. It's also useful for interview preparation and coding challenges.

💡 Use backtracking to find all unique combinations that sum up to a target value, and sort the candidates array to handle duplicates
