Sharing Leetcode Solution

After last week, I have hosted 5 sessions on solving leetcode together. A bunch of easy questions, 3 medium questions and 1 hard question.
I learnt a lot during the sharing. There are basic concepts that I didn't fully understand but I start using. Sometimes I assumed my thoughts are fully explained while the reality is that those thoughts never get out of my head. My sharing sometimes only consider my understanding rather than take audiences' pace into consideration.
Most importantly, I realized the difficulty of explanation. If solving leetcode questions requires some understanding on the techniques needed for solution, then sharing and even teaching require understanding of the concepts to not only details but also one symbol. Questions could be from anywhere or about anything. I could still be able to adapt, sometimes I get prepared while other times I will look up the questions and test them out together with my friends.
I was suggested about an extension called LeetHub, which is useful not only that it help me upload my submission on leetcode to GitHub. But it also contains the problem description and all graphs. This makes things a lot better.
Next week I need to leave for a travel so I have to pause. Will continue when I get back. Ohh I should start video explanation which saves time (maybe).
