#Day 15: Insert, Delete, find max in Stack

The days when you are unable to solve sufficient problems turns out really disappointing.
It wasn't a great day. I just solved only one question related to insertion, deletion and finding maximum element in Stack. I am stuck in 4 questions and this is kind of disappointing. The fact that they are labelled Easy on GFG is making me feel more sad. I'm unable to meet the Time and Space complexity of these questions. I hope I'll be able to solve these questions by tomorrow.
