Documenting my DSA journey 📚 | C++ • LeetCode • CS Student | Learning in public

[Pankaj Bisht @BytesByBisht]

Completed Quick Sort using recursion in C++. Another step forward in strengthening recursive thinking, divide-and-conquer, and efficient algorithm implementation. Continuing to solve LeetCode problems alongside DSA practice.

@Sehehhejj Honestly, I still find myself going for brute force a lot. And I’m actually happy when I can get that approach working first. The hard part for me is sometimes figuring out how to transition from brute force to the optimal approach.

Completed Merge Sort using recursion in C++.

Another step forward in understanding recursive thinking, divide-and-conquer, and implementation. Continuing to solve LeetCode problems alongside DSA practice.

@Sehehhejj The result wasn't in our favor, but the effort everyone put in definitely was. Proud of the team. 🤝

[Pankaj Bisht @BytesByBisht]

Continuing my Recursion journey in C++.

Implemented recursive array/string reversal and recursive Bubble, Insertion, and Selection Sort. Consistently solving LeetCode problems to strengthen recursive thinking and implementation.

#DSA #LeetCode #Programming

[Pankaj Bisht @BytesByBisht]

Learning Recursion in C++ one topic at a time.

Finished recursive Linear Search and Binary Search, and solved a few recursion problems for practice. Each question is helping me think more recursively and improve my problem-solving.

#DSA #LeetCode #Programming

[Pankaj Bisht @BytesByBisht]

Started learning Recursion in C++.

Understanding the basics of recursion, recursion trees, and how stack memory works during recursive function calls.

Getting a better understanding of how each function call is stored and resolved in the call stack.

#DSA #LeetCode #Programming

[Pankaj Bisht @BytesByBisht]

Finished learning Macros, Global Variables, Inline Functions & Default Arguments in C++.

Small concepts, but understanding how they work under the hood makes writing cleaner and more efficient code.

One step closer. 🚀

[Pankaj Bisht @BytesByBisht]

@Sehehhejj Great session today! 🔥 Excited to be part of this team and looking forward to turning our ideas into something meaningful. Let’s build! 🚀

[Pankaj Bisht @BytesByBisht]

Finished learning Dynamic Memory Allocation of 2D arrays in C++ — creating, input/output & manual deletion.

Grasping these concepts makes multidimensional arrays much clearer and less error-prone.

Progress feels good 👍
#DSA #LeetCode #Programming

[Pankaj Bisht @BytesByBisht]

Finished learning Reference Variables and the basics of Static vs Dynamic Memory in C++.

Understanding how memory is managed makes a lot more of the language click.

One step closer to writing better code.

On to the next topic.

@Sehehhejj Hey Sahaj, let's connect!

[Pankaj Bisht @BytesByBisht]

@Superman_MW Thanks man! Motivation comes and goes. Build the habit instead. Looking forward to seeing your progress too. 🚀

[Pankaj Bisht @BytesByBisht]

Finished Double Pointers in C++.

Solved a few two pointers and pointer problems. The concepts are starting to feel much more natural with practice.

On to the next topic.

#DSA #LeetCode #Programming

[Pankaj Bisht @BytesByBisht]

Finished Pointers in C++.

Revised every DSA topic I've learned so far and went back to solve questions that I couldn't crack on my first attempt.

This time, I was able to solve a few of them on my own. It's nice to see the effort starting to show.

#DSA #LeetCode #Programming

[Pankaj Bisht @BytesByBisht]

Finished Basic Maths for DSA: Sieve and Modular Arithmetic.

Solved a few medium LeetCode questions on my own and learned a lot from the ones I couldn't.

Slowly building confidence, one topic at a time.

#DSA #LeetCode #CPP #Programming

[Pankaj Bisht @BytesByBisht]

Completed 2D Arrays in C++.

Worked through medium-level questions and solved a few completely on my own.

Went back to revise previous topics and finally figured out some problems that had stopped me earlier.

Small improvements every week are starting to add up.

#DSA #LeetCode

[Pankaj Bisht @BytesByBisht]

Took a break from posting, not from learning.

Revisited old LeetCode problems, worked on writing better solutions, and learned Char Arrays & Strings in C++.

Medium problems still take time, but I'm getting better at breaking them down.

#DSA #LeetCode #CPP #Programming

[Pankaj Bisht @BytesByBisht]

Completed STL in C++.

Solved LeetCode problems from different topics I've learned so far and applied multiple concepts together.

Problems that once felt overwhelming are starting to feel more approachable.

Progress is becoming easier to see.

#DSA #LeetCode #CPP #Programming

[Pankaj Bisht @BytesByBisht]

Finished Bubble Sort Selection Sort and Insertion Sort.

Revisited older questions and solved the ones that had blocked me before.

Now starting medium sorting problems to improve pattern recognition.
