Weekly Coding • 2025-06-24

Hello everyone. It's time for a new entry in my diary.

Last week, I spent 4 hours on LeetCode and 5 hours on digital painting.

LeetCode 💻 Completed 3 problems:

• 105. Construct Binary Tree from Preorder and Inorder Traversal
  • I reached test 198 out of 203, and the remaining tests my program was running too slowly. I had to read the online hint.
• 106. Construct Binary Tree from Inorder and Postorder Traversal
• 107. Binary Tree Level Order Traversal II

Digital Painting 🖼️ Made several small drawings in ComfyUI and uploaded them to Pixiv in one batch. Collected 10 stars for the week.

Personal Website 🌐 It crashed. It turned out that my Tailscale Funnel login had expired. I managed to resolve the issue by logging in again, but the URL changed afterward. I had to edit the frontend... 🤔

As always, there's not enough time for all projects. I need time both for painting and coding. Currently, I'm also undergoing driving school lessons, so my free time is even more limited 🚿.
