TIP102 Unit 3 Session 1 Standard (Click for link to problem statements)
Understand what the interviewer is asking for by using test cases and questions about the problem.
Plan the solution with appropriate visualizations and pseudocode.
General Idea: Utilize a stack to reverse the order of the comments in the queue.
1. Initialize an empty stack to temporarily store the comments.
2. Iterate through each comment in the input list:
1. Push each comment onto the stack.
3. Initialize an empty list to hold the reversed comments.
4. Pop elements from the stack one by one, appending each to the reversed comments list.
5. Once the stack is empty, return the reversed comments list.
⚠️ Common Mistakes
def reverse_comments_queue(comments):
stack = []
reversed_comments = []
for comment in comments:
stack.append(comment)
while stack:
reversed_comments.append(stack.pop())
return reversed_comments
