"The task requires implementing a Stack with constant time operations including finding minimum. \n",
"To achieve O(1) for getMin(), we need to maintain a second stack that keeps track of minimums.\n",
"Each time we push, if the value is smaller than current min, we add it to minStack.\n",
"When we pop, if the popped value equals current min, we also pop from minStack.\n",

"Status: NEEDS_IMPROVEMENT\n",
"Feedback: \n",
"While the implementation is generally correct and achieves O(1) time complexity for all operations, there are several areas for improvement:\n",
"\n",
"1. Error Handling:\n",
"- pop() should raise an exception when stack is empty rather than silently returning\n",
"- getMin() should raise an exception when stack is empty rather than returning None\n",
"- These behaviors should be consistent with standard stack implementations\n",
"\n",
"2. Type Hints:\n",
"- Return type hint for pop() should be None or void\n",
"- Missing type hints for class variables stack and minStack\n",
"\n",
"3. Documentation:\n",
"- Missing docstrings for class and methods\n",
"- Missing parameter descriptions\n",
"\n",
"4. Edge Cases:\n",
"- No explicit handling of invalid input types for push()\n",
"\n",
"The core algorithm is correct and efficient, but the implementation could be more robust and better documented for production use.\n",

"Based on the feedback, I'll improve the implementation by:\n",
