  Master Linked Lists for Coding Interviews: 8 Must-Solve LeetCode Problems ⏱️  Estimated reading time: 16 minutes When you think about how software engineers work with data, they will tell you that data rarely behaves in an organized pattern (like a neat row of boxes); instead, data tends to grow, shrink, move around, and be very demanding regarding its flexibility. Linked lists were designed to solve this problem. A linked list is a linear data structure in which each piece of information called a node has two parts: 1) The piece of information that you want to store and 2) The address or reference to the address of the next node in the list so that the first and second nodes are linked together. Linked lists do not store the nodes in contiguous memory, thus eliminating time-consuming processes because insertion or deletion of nodes does not consist of shifting large numbers of nodes. Because linked lists are dynamic by nature, linked lists are used extensively withi...

Make It Obvious: The Invisible Rule That Controls Every Habit You Build

 

Blog 7: Habits Don’t Start Big — They Start Invisible.
“You don’t fail to build habits because you’re lazy — you fail because you didn’t see them begin.”

🧠 What’s pulling your strings without you noticing?

You pick up your phone.
You scroll.
You binge.
And you don’t even remember starting.

That’s the power of the cue — the invisible spark behind every habit, good or bad.
Law 1 of Atomic Habits: Make it obvious.
Let’s break it down, not like a textbook — but like how you and I live it.

🎯 PART 1 — Notice it before you can fix it

Most of us try to change habits like we’re fixing the output.
But the real switch? It flips when you notice the input.

That’s the cue — the moment before the moment.

💡 How to catch a habit in the act?
Use what I call the Call-Out-Loud Method
Whenever you catch yourself doing something on autopilot, say it aloud:
“I’m unlocking my phone without reason.”

It sounds silly — but it brings the unconscious into the light.
And that’s where habits lose their invisible shield.

📂 PART 2 — Plan it. Stack it. Make it automatic.

Once you’ve caught the cue, now you train it — like a pet.

🔸 Rule 1: Give it a timestamp and a home
“I will [do this] at [time] in [place].”

This removes friction.
This removes "kal dekhte hain".

Example:
“I’ll revise Physics at 7 PM on the dining table.”

🔸 Rule 2: Stack it like Jenga
“After [existing habit], I will [new habit].”

Example:
“After brushing, I’ll drink a full glass of water.”

Why does this work?
Because your brain already trusts the first habit — and it pulls the second along.

📍 PART 3 — Environment isn’t background. It’s the stage.

Habits don’t exist in a vacuum.
They’re planted in the soil of your surroundings.

🌱 Here’s the golden rule:
Assign one purpose to one space:
- Bed → sleep
- Desk → work
- Dining table → eat

Mixed environments = mixed focus = broken flow

If a place is confusing your brain, don’t fight harder — redesign smarter.

❌ PART 4 — Want to break a habit? Starve the cue.

You don’t need more motivation.
You just need less exposure.

Try this:
- Console goes in the cupboard
- YouTube tab gets removed from your bookmarks
- Junk food? Out of the house

Out of sight.
Out of reach.
Out of loop.

That’s how bad habits starve.

🗺 The Real Shift?

Most people chase the reward.
Smart people control the cue.

Because when you see the start,
you don’t lose control of the middle.

✒️ Closing Whispers 🖊️
What triggers us is rarely loud,
It hides beneath the daily crowd.
But those who sense its quiet sound,
Reclaim the ground where they were bound.

Jee Honest Journey

 I Dreamt of IIT Bombay – This Is What Really Happened after 10th, I had just one dream in mind — IIT Bombay. Right after my board exams, I joined coaching classes in Pune. My father used to talk about IIT Bombay every single day. The goal was clear, the ambition strong — but the journey turned out to be very different from what I expected.Coming from a state board background, my basics were not strong. I struggled to understand theory, and as a result, I couldn’t solve many questions. Still, I used to complete all module exercises before anyone else. People were surprised by the speed, but the truth was, I couldn’t make it beyond the third batch. Some of my friends kept moving to higher batches. I felt jealous, frustrated, and often questioned my own capabilities. Then came May — I gave my first full portion test. The result was a shocker. I wasn’t even qualifying for Mains. That’s when I changed gears. I stopped focusing on Advanced and started preparing specifically for Mains — ...

The hidden price of starting late for the exams like JEE

Dangerous Delay: Why Starting Late in Competitive Exams Can Be a Huge Mistake :- In our previous blog, we explored the raw and personal story of a student who gave everything for JEE — clearing Mains but falling short in Advanced. It wasn't a lack of effort, but a gap in timing and strategy that led to regret. But what about the students who never even get the chance to push that far? After publishing the first blog, some readers opened up about their own struggles - and their stories revealed a deeper truth : failure doesn't always come at the end of the race. Sometimes, it begins right at the starting line.  ⏳ When the Clock Starts Too Late :- Competitive exams like JEE aren’t just about how hard you work — they’re about when you begin. There’s a misconception that one can start preparing seriously in Class 12 and still make it. A few might pull it off, but for most, that delay proves costly. Several viewers shared how they began their serious preparation during Class 12, whi...

Time and Space Complexity Explained: A Practical Guide with Python Examples

Image
  Time Complexity & Space Complexity Before we talk definitions, let’s slow down and ask the questions that actually matter . Why should you even care about Time and Space Complexity? Why does your code work perfectly for 100 inputs but crash or freeze at 1 million? Why does the same logic pass locally but fail on online judges ? Why do companies reject solutions that give the correct output? Why does a feature work in development but struggle in production? Why do two programs doing the same task feel wildly different in speed? The answer hides in plain sight. Time Complexity decides how fast your idea scales. Space Complexity decides how heavy that idea becomes. If you ignore them, your code may run today and collapse tomorrow. In the world of coding, ideas are cheap. Execution is everything. And execution is judged by two silent judges sitting in the back row of every interview, every competitive test, every production s...
