Master Linked Lists for Coding Interviews: 8 Must-Solve LeetCode Problems

  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...

Ahmedabad Plane Crash 2025 : Air India Flight Crashes After Takeoff, 241 Dead

 The Ahmedabad Plane Crash: A Costly Reminder That We Can’t Afford to Ignore


On June 12, just minutes after taking off from Ahmedabad airport, an Air India Boeing 787-8 crashed into the BJ Medical College hostel mess — barely 5 km from the runway. Out of 242 passengers on board, 241 didn’t survive. The only survivor, Vishwakumar Ramesh, was on his way to London with his brother — who didn’t make it.


Among the victims was the Chief Minister of Gujarat, along with hundreds of other innocent lives, including students in the hostel building. It’s a devastating event — not just because of the number of lives lost, but because it exposes something deeper: a brutal example of systemic negligence.


This wasn’t bad luck. A plane doesn’t just fall out of the sky without warning. Something failed — whether in maintenance, checks, or basic responsibility. And this time, that failure cost lives. A lot of them.


The Directorate General of Civil Aviation (DGCA) has launched an investigation into the technical and procedural lapses that may have led to this disaster.


The Tata Group has announced ₹1 crore compensation for families and will cover the medical treatment for survivors. That’s appreciated. But compensation doesn’t fix broken trust.


Even Prime Minister Narendra Modi and Home Minister Amit Shah visited the crash site and met with officials and victims' families — a gesture that shows the scale of the tragedy and the national attention it has drawn.


This isn’t just another tragic headline. It’s a reminder that even systems we trust the most can let us down — and when they do, the price is often paid by those who had nothing to do with the failure.


Air India, already under scrutiny in the past, now faces even deeper questions about how such negligence was allowed to slip through.


We aren’t here to create panic. We’re here to ask questions. Because silence doesn’t prevent disasters — it only delays the next one.

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...
