Hiii!, Welcome to Day 2 "Knowledge has to be improved, challenged and increase constantly, or it vanishes" What Problem is in focus 1. Add 2 numbers 2. Modify Prob #1 using a HashMap implementation. To get started with problem 2 on leetcode, I need to understand HashMaps and Linked List Learnt what are hash-maps, arrays and python fundamentals. Currently thinking should I start from scratch with python or continue leetcode exercise in typescript? For solid execution, I started on a exercise for python arrays hands-on Learning today I have to read the question text properly and try to come up with a simple solution. Ran into issue understanding the question and added unnecessary complexity to the solution. As Python learning is expansive and would require detailed notes, I have started this notion doc to document my learnings Takeaways from today's learning 1. Read Question Properly : understand text, subtext before getting started on a solution 2. Keep it Simple...
