Good evening. It is time to write the weekly report. Last week, I did the following in my free time:

  • LeetCode tasks 🖥️ 9 hours
  • Foreign language 🇩🇪 8 hours

I completed the following LeetCode problems:

  • 89. Gray Code ⌚ spent 46 minutes 📊 speed 55%
  • 90. Subsets II ⌚ spent 32 minutes 📊 speed 67%
  • 91. Decode Ways 🎫 spent 44 minutes 📊 speed 70%
  • 92. Reverse Linked List II ⌚ spent 1h 53m 📊 speed 100%
  • 93. Restore IP Addresses ⌚ spent 33 minutes 📊 speed 71%
  • 94. Binary Tree Inorder Traversal ⌚ spent 28 minutes 📊 speed 64%
  • 95. Unique Binary Search Trees II ⌚ spent 2h 46m 📊 speed 37%
  • 96. Unique Binary Search Trees ⌚ spent 1h 21m 📊 speed 100%

In total, I completed 8 problems:

  • Independently without hints 🟢 5 tasks
  • Completed with a hint 🟡 3 tasks. These were frustrating ones.

I plan to reach problem number 100 and then switch to some other mini-project.

I found out about a change in the Yandex Disk rules: they are canceling unlimited photo storage, and all photos have moved to the limited segment of the disk… After that, my disk immediately became more than 100% full. Now I need to think about what to do with my files. I’m thinking about organizing a home storage system without relying on “the cloud.”
