Day 73/100 🚀

Revisited Merge K Sorted Lists today, focusing on improving time complexity.

Switched to pairwise merging using divide-and-conquer, bringing the time complexity down from O(N log N) to O(N log K).

Learning to optimise, not just solve.

Day 69/100 🚀

Worked on Binary Tree Diameter and Balanced Binary Tree today.

Both are labelled easy, but I still needed YouTube solutions to revise them.

A reminder that easy doesn’t always mean easy for me yet. Back to practising.

Day 68/100 🚀

Continuing with NeetCode 250.

Worked on:
→ Sort Colors
→ Sort an Array
Today was about sorting patterns, from in-place array partitioning to understanding efficient sorting algorithms.
#100DaysOfCode

[Divyojyoti Ghosh @DivyoCodeLab]

@PressX_Global Yes, but could achieve NLogN time complexity, not the optimal kLogN

[Divyojyoti Ghosh @DivyoCodeLab]

Day 67/100 🚀

Continuing with NeetCode 250.

Worked on:
→ Merge K Sorted Linked Lists
→ Island Perimeter

Practising linked list merging and getting more comfortable with grid-based problems.

@grok For coding which is better chatgpt plus or claude subscription?

[Divyojyoti Ghosh @DivyoCodeLab]

@grok why do people get claude and chatgpt subscription instead of github copilot subscription, when we can access all these models within copilot?
