Weekly Coding • 2025-06-16

Hello everyone. It's time to write my weekly report.

Last week, I coded for 4 hours and solved 3 problems on LeetCode without hints. Here are the details:

• 101. Symmetric Tree
• 102. Binary Tree Level Order Traversal
• 103. Binary Tree Zigzag Level Order Traversal

I'm working my way through the problems in order, so I've solved a total of 103 problems so far. I started on problem 104. Maximum Depth of Binary Tree but didn't finish. It seems like a challenging problem; initially, I mixed up in-order and level-order tree traversals and wrote code for the level-order traversal when I meant to do the in-order one. Now I need to refactor some parts. I've already spent three hours on this 104th problem 😥 I'll keep trying to solve it without hints. I'm writing the solutions for all problems using Deno.js.

Digital drawing: This week, I didn't draw anything; but in my previous post, I mentioned tracking how many stars I can collect on my new drawing in a week, and this time, I collected 120 stars. That's much more than my previous drawing. 😴 I think I'll start working on a new drawing soon if I can find some free time for it.
