"The task requires implementing a Stack with constant time operations including finding minimum. \n",
105+
"To achieve O(1) for getMin(), we need to maintain a second stack that keeps track of minimums.\n",
106+
"Each time we push, if the value is smaller than current min, we add it to minStack.\n",
107+
"When we pop, if the popped value equals current min, we also pop from minStack.\n",

"Feedback: \n",
141+
"While the implementation is generally correct and achieves O(1) time complexity for all operations, there are several areas for improvement:\n",
142+
"\n",
143+
"1. Error Handling:\n",
144+
"- pop() should raise an exception when stack is empty rather than silently returning\n",
145+
"- getMin() should raise an exception when stack is empty rather than returning None\n",
146+
"- These behaviors should be consistent with standard stack implementations\n",
147+
"\n",
148+
"2. Type Hints:\n",
149+
"- Return type hint for pop() should be None or void\n",
150+
"- Missing type hints for class variables stack and minStack\n",
151+
"\n",
152+
"3. Documentation:\n",
153+
"- Missing docstrings for class and methods\n",
154+
"- Missing parameter descriptions\n",
155+
"\n",
156+
"4. Edge Cases:\n",
157+
"- No explicit handling of invalid input types for push()\n",
158+
"\n",
159+
"The core algorithm is correct and efficient, but the implementation could be more robust and better documented for production use.\n",
