Day 20 - TA Lecture, Leetcode & Logged My Run

Woke up early again today. Slowly building a routine.

Did a short full-body conditioning session (~20 minutes), and then went for a quick run.

Ran 4k — not bad at all 💪
Starting today, I’m going to log my runs and walks regularly.

Came back, showered, made coffee, and spoke to my mom before heading out to university.

Had my TA lecture today.
Topic was Information Security — a few new concepts and terms I noted:

  • Stuxnet
  • Social Engineering
  • STRIDE and DREAD threat modeling frameworks

Interesting stuff!

Stayed on campus for a while and then came back home.

Leetcode Practice

Revisited 53. Maximum Subarray
- Just reinforced Kadane’s Algorithm
- Starting to feel more natural now

Then solved 56. Merge Intervals

  • Initially assumed the input was sorted — turns out it wasn’t
  • So sorting first is essential
  • But my approach still made sense and worked after that step

For some reason, I instinctively feel like I’ll be asked one of these in a future interview, lol.

Kafka Learning

Continued with my Kafka deep dive.

Just documenting daily learnings so it’s easier to revise and reflect.

Wrapped up the evening by applying to a few more jobs and went to bed early.

Got everything I wanted to do done today.
Feeling good. Small wins.
