Min Stack Comments


  • my code

    I'm not sure how I'm supposed to restart the current min and set it to 7. Basically if i pop a bunch off and the new min is a bigger number it is still showing the current min i set from before. Any hints on what I'm doing wrong?

  • So, how do I know if all my operations are correctly running at O(1)? I mean, I can say it in theory but do the platform perform any basic check? Doesn't looks like because any code I wrote the test is passing.

  • @Paulo, currently you should analyze the running time on your own. The computer cannot check the running time, but in the future we may add larger tests cases that fail to complete in time for poor algorithms.

  • I still don't know exactly what I'm doing wrong...

  • would it be easier to use a queue here?

  • Not directly related to the question, but it would be pretty helpful if you could directly reply to other comments in threads

  • Hint: Constant running time, but not constant space complexity

  • Please a hint. i cant figure it out. I keep sitting with an empty stack and other problems. Help.

  • I have fount a way, but i think its not really the good way. can i see a featured awnseranywere?

  • Here's a possible solution.

  • Would have been nice if the system didn't think my solution was wrong just because I forgot to println() after each example. Otherwise, keep up the good work!

  • i write the program in Big O O(1) .how i can see my extra credit score.

  • All correct answers get the same mark, but it's a personal challenge to see if you can get a good Big-O time.
