finals are coming up, but I don't want to break my DSA consistency. so, for the next few days, the goal is simple: at least 1-2 good questions every day alongside exam prep.
also, I think X is a great accountability partner, so I'll be posting daily logs here starting today.

#day03
Before I go back to exam cram:
Solved an easy Postorder Traversal of Binary Tree (using 2 stacks) question and wrapped up the POTD.
Back to the exam grind now. Wish me luck for tomorrow!

[Nulll Komalll @nulllkomalll]

So I started posting my own journey too. Coding, exams, projects, the occasional win, and plenty of struggles.
Still not consistent though 😛

My X lore:

On a random afternoon, I opened X and started scrolling. I saw people sharing tech stuff, building cool things, random experiences, failures, jokes, and whatever was happening in their lives. The community felt surprisingly healthy and genuine.

Share the lore of you joining X 👀

Here's mine:

Since joining college, I always struggled to find ambitious, like-minded people around me.

I thought joining clubs would help, so I joined pretty much every good tech club in my college hoping to connect with people who were building cool things and seniors I could learn from.

But even after that, it still felt like something was missing. The environment I wanted just wasn't there.

That's when I decided to join X.

I wanted to stay updated with what's happening in tech, but more importantly, I wanted to be around people who were building, learning, and sharing their journey publicly.

Since the beginning, my goal wasn't just to consume content but to create it as well

I also wanted a place to document my journey. It helps me track progress and stay accountable

So on December 9, I started the #100DaysOfCode challenge.

One post a day. Just showing up and sharing what I was learning.

And it worked.

I completed the challenge, made some great friends along the way, and found the kind of environment I was looking for in the first place.

Today, 1.5k+ people are following along with my journey, which is honestly something I never expected when I made that first post.

Your turn :)

#day02
came back from exams. spent the afternoon resting. did level order and binary tree traversal lc questions today. (unsatisfied tho). now i just want to get through 1 unit tonight.🥀

[Nulll Komalll @nulllkomalll]

dsbda finals done ✅
paper was good, but way too lengthy 😭
also kinda funny almost everything came straight from the pyqs.
midsems went well, endsems felt good too. maybe the score is gonna be nice this time 🤞
next one day after tomorrow.

#day01

Did 3 binary tree traversal questions today. Pretty easy start.
The rest of the day went into exam cramming. Still got 2 units left to go through!

[Nulll Komalll @nulllkomalll]

Glad I did today’s contest. Good reminder that I still need to improve a lot on problem modeling and pattern recognition.

Today's Leetcode Contest summary: WC 504

here's how i approach q1(easy), q2(med done), q3(partially)

@AnushkaDesign honestly, so good this is!!! loved the clean UI

[Nulll Komalll @nulllkomalll]

@chiraggksh @Divyansh_273 Yep noted!! I started trees yesterday, will definitely come back to recursion again.

[Nulll Komalll @nulllkomalll]

in search of my, “ohhh… function bas smaller problem solve kar raha hai.”

[Nulll Komalll @nulllkomalll]

@Divyansh_273 i never thought of using trees specifically to build recursion intuition, but now that you mention it, recursive trees probably make way more sense visually. gonna try DFS questions next.

[Nulll Komalll @nulllkomalll]

@consoleloglifee yess for sure!!

[Nulll Komalll @nulllkomalll]

today's learnings, also drop your suggestions to these.

[Nulll Komalll @nulllkomalll]

Anyone else feel simulation/bruteforce questions become more about modeling states correctly than coding itself 😭

[Nulll Komalll @nulllkomalll]

Today’s contest summary: WC 503

Solved first 2 questions pretty fast.

Then Q3 happened.
I was THIS close to solving it… until edge cases and runtime errors decided to humble me publicly.

[Nulll Komalll @nulllkomalll]

wanted to apply for Amazon HackOn 2026 but my college isn’t even in the organizations list. gatekeeping won’t stop the grind ):

[Nulll Komalll @nulllkomalll]

ngl, these days i’m actually enjoying leetcoding.

doing it daily genuinely feels good now. even on days i miss it somehow, i make myself solve at least one problem before sleeping.

consistency & discipline.
