A valid partition divides every array element between two subsets with the same total. ## Examples - **Input:** `[2, 4, 11, 5]` **Output:** `True` **Explanation:** The array can be partitioned into `[2, 4, 5]` and `[11]`, and both subsets sum to 11. - **Input:** `[2, 7, 3, 1]` **Output:** `False` **Explanation:** The array cannot be partitioned into two subsets with equal sums. ## Question workspace The question includes tabs for **Question**, **Solution**, and **Community**.
