Day 16 of #100DayOfCoding | 15-06-2026

Today I completed Lectures 3,4,5 of stack playlist and did its corresponding problems i.e
- Valid Parentheses
- Next greater element I
- Min-Stack
Today's day was a quite productive one comparatively.
Looking forward to maintain the same.

Day-15 of #SDESheetChallenge.
I have not started greedy algorithm still, so it was a bit of a messy today.

I understood some code and able to figure out the basic logic. The N-meeetings and max-platforms were pretty much understandable but the other two were quite challenging.

for students reading my story:

don’t copy my path. build your own.

don’t chase salary screenshots, or someone else’s timeline.

start with one skill. get dangerously good at it. build projects. read docs. ask better questions. learn in public. take boring fundamentals seriously.

most people don’t lose because they lack talent.

they lose because they keep changing direction before compounding starts.

Completed Lecture 4 and 5 of Striver's Stack and Queue playlist.
LC-496 Next Greater Element I
LC-155 Min Stack

First question is based on Monotonic Stack which was an easy one, the second one was based on basic Stack approach but I got stuck in syntax.

Day 16 in progress.

Amazing journey, my eyes are filled with tears while reading this article, the struggle , the pain , the sacrifices before the final victory which needs to be understood is written in an amazing way.

Hat's off bro, great journey🫡.
Thanks for the guidance as your junior.😊

@kaushpathe @ChaiCodeHQ @piyushgarg_dev @Hiteshdotcom I was asking about the application you were solving the dev-part😅

[Chandan @dev_chandan21]

Completed Lec-03 of Stack and Queue, a bit lengthy lecture.
Learnt about conversion from Prefix, Infix and Postfix.
Finishing this lecture was easy but remembering all the conversions is quite a challenge :)

Progressing a bit by bit

Day 16 in progress.

[Chandan @dev_chandan21]

Solved Valid-Paranthesis (LC-20)
This problem is just checking every parameter like a brute-force, nothing much in this question.
The main part of the question is to figuring out that this question should be solved through Stack

Day-16 in progress.

#DSA #LearnInPublic

[Chandan @dev_chandan21]

Starting off the day with LC - Daily question
Easy question based on LinkedList.

[Chandan @dev_chandan21]

Day 15 of #100DaysOfCode | 14-06-26
Solved all three problems of #SDESheetChallenge.
Lectures:
Lecture 1,2 and 8 (because today there was a question related to stack in #SDESheetChallenge) i.e Trapping rain water, so I did that lecture too :)

Made notes of these lectures.

[Chandan @dev_chandan21]

Day14✅ #SDESheetChallenge
1) Trapping Rainwater - Running maxL & maxR
2) Remove duplicates - Two pointers method
3) Max consec 1's - comparing indexes

Trapping Rainwater was a good one to solve, watched striver's lecture to solve that problem.

As AI subscription costs keep rising, “AI Allowance” might become a standard component of compensation.

That future doesn’t seem very far away.

🗓️DAY-13 #SDESheetChallenge
@takeUforward_
@striver_79
Solved the following questions for today:
1.3SUM
2.Clone a LL with random and next pointer
3.Rotate a LL

Most AI coding tools still work like this:

They write the code.
Then you debug it.
Then you test it.
Then you fix it.

If humans still have to verify everything, that’s not autonomy.
That’s autocomplete with confidence.

Day 13 of #100DaysOfCode | 12-06-26
Solved all three problems of #SDESheetChallenge.

[Chandan @dev_chandan21]

Day 12 of #SDESheetChallenge completed:
✅ Find starting point in LL
✅ Flattening of LL
✅Check palindrome
> Struggled with 3rd one . Took lot of time and efforts there, palindrome ques was a easy one.

Day 11 of #100DaysOfCode | 10-06-26
Solved all three problems of #SDESheetChallenge.
That's all I did today. Exhausted because of some college work but the good news is today was the last working day, so I can give my full focus on DSA until my Sem exams :)

[Chandan @dev_chandan21]

Day 11 of #SDESheetChallenge
✔️Find the intersection point of Y LL
✔️Detect a loop in LL
✔️ Reverse LL in group of given size K

First two problems were easy, but the third one was not tough to be specific but took some time to figure out the syntax.
