Activity Log
Jun 6, 2026

Slow kind of day. Running behind the schedule, need to ramp up the pace. Completed first problem of Neetcode 150. First ever leetcode style problem solved, milestone!

Let’s push a bit more tomorrow to catch up!

Jun 5, 2026

A bit behind the schedule. Small hiccup at the start. Completed the Arrays section of Neetcode DSA. Will focus on solving the suggested problems first, then begin the problems list from Neetcode 150. Also, catchup with Node.js Buffers and Hands-On LLM Ch. 1.

TIL :

  • Why do we double the capacity of an array every time we resize a dynamic array, instead of increasing by 1 or any arbitrary number?
  • Amortised Time Complexity
Jun 4, 2026

Day 1 of a long journey. Subscribed for access to Neetcode Lessons. Went through the first lesson on RAM. Did some tweaking on the vault repo to make the deploy pipeline work. Today was more of a preparatory day. Tomorrow, will complete the Arrays section of Neetcode DSA and the suggested problems. Need to get acquainted with Python syntax just enough for the coding problems. Some lessons on Node.js buffers and the start of Chapter 1 of Hands-On LLMs. Slow and steady wins the race!
