Weekly Coding • 2026-03-30

## Weekly Progress Report: **LeetCode:** Spent **8 hours** on LeetCode this week. Completed challenges **201 to 207** in TypeScript. Aiming to reach challenge #210 by the end of the week, but didn't make it. * **201. Bitwise AND of Numbers Range:** Medium (Passed) - Completed independently. * **202. Happy Number:** Easy (Passed) - Completed independently. * **203. Remove Linked List Elements:** Easy (Passed) - Completed independently. * **204. Count Primes:** Medium (Failed) - Attempted independently, but encountered Time Limit Exceeded due to using a brute-force approach. Explored the Sieve of Eratosthenes algorithm. * **205. Isomorphic Strings:** Easy (Passed) - Completed independently. * **206. Reverse Linked List:** Easy (Passed) - Completed independently. * **207. Course Schedule:** Medium (Failed) - Attempted independently, got stuck with Time Limit Exceeded. Researched Depth-first search algorithms for detecting cycles in graphs. **Personal Website:** No coding this week, but noticed an issue with my AI-powered post translation feature. It's randomly failing to translate posts into other languages. Need to investigate and fix this. **Console Bugs:** Found a frustrating bug in **Windows Terminal** from Microsoft Store. Leaving the terminal open for 24 hours causes significant CPU usage and performance degradation. Switched to **ConEmu**, but it also has its own set of issues. It seems incredibly difficult to find a bug-free terminal solution on Windows.
