LeetCode Discipline: Number Complement Solution

Ever faced a memory leak… in code or in life? 😂 Post: In C, forgetting to free() memory leads to leaks. In life, forgetting to “let go” does the same. 🔹 Deleted the node 🔹 But memory still occupied That’s not just a bug… that’s emotional engineering 😄 👉 Lesson: Always clean up your pointers (and your past) #CProgramming #LinkedList #MemoryLeak #CodingHumor #SoftwareEngineering #EmbeddedSystems #DebuggingLife #TechMemes #ProgrammerLife

Claude Code Tip #12 / 100 — Context is your most valuable resource. Burn it carelessly and Claude starts making mistakes. A single debug session can consume tens of thousands of tokens. Once the context window fills up, Claude begins "forgetting" earlier instructions — and the errors multiply fast. This isn't a bug. It's physics. Every best practice in Claude Code exists for one reason: keep the context lean. That's why you /clear between unrelated tasks. That's why you use subagents to offload research. That's why you write concise CLAUDE.md files instead of dumping paragraphs of instructions. Think of context like RAM. You wouldn't run 50 Chrome tabs while compiling a large codebase. Same principle applies here — the more you stuff in, the slower and sloppier things get. Treat every token as a decision. Ask yourself: does this actually need to be in the conversation, or can I handle it another way? The developers who get the most out of Claude Code aren't the ones who write the longest prompts. They're the ones who manage context deliberately. #ClaudeCode #AITools #DeveloperProductivity #Programming #SoftwareDevelopment

LeetCode Practice: Today I solved Problem no.328(Odd Even Linked List) Statement- We are given the head of a singly linked list , group all the node with odd indices together followed by the node of even indices , and return the reordered list. Approach(Brute Force) Key Idea: I used ana auxiliary array to store the node values 1-Traverse the list by using temp->next->next starting from head to collect the odd indexed nodes 2-Then temp=head->next and traverse it using temp->next->next to collect the even indexed nodes 3-This ensures that all the odd index were stored first followed by even indexed nodes 4- Finally convert the array into the linked list. Time Complexity: O(N) Space Complexity: O(N) (due to the extra array) #LeetCode #DataStructures #LinkedList #CodingPractice #DSA #Programming #ProblemSolving

Claude Code Tip #11 / 100 — Before you start a new task, run /clear. Every time. Most people don't do this. They pile new requests on top of old context and wonder why Claude starts making weird decisions halfway through. Here's what's happening: Claude's context window is finite. The more irrelevant conversation history sitting in there — old debug sessions, previous refactors, questions you already got answered — the more it dilutes the signal on your current task. Claude starts "forgetting" instructions it saw earlier. It makes mistakes it wouldn't make on a fresh session. Run /clear at the start of every unrelated task. It takes 5 seconds. The alternative is spending 30 minutes watching quality gradually degrade, then starting over anyway. I use a simple rule: if the new task touches different files or has different goals, it gets a fresh context. Same feature, same session. Different concern, /clear first. Don't treat context like it's free. It's the most expensive resource in your workflow. #ClaudeCode #AITools #DeveloperProductivity #Programming #AIEngineering

Can you predict the behavior of this program? #include<stdio.h> #include<stdlib.h> int main() { int *p; { p = malloc(sizeof(int)*5); for(int i = 0; i < 5; i++) p[i] = i; } free(p); } #c #embeddedc #cprogramming #pointers

🚀 𝗗𝗮𝘆 𝟭𝟵 𝗼𝗳 𝗺𝘆 #𝟳𝟱𝗗𝗮𝘆𝗦𝘁𝗿𝗶𝘃𝗲𝗿𝗔𝟮𝗭𝗦𝗽𝗿𝗶𝗻𝘁 Today I solved a couple of interesting problems that required careful observation and string-processing techniques. What I focused on today: • C. Advantage – computing the difference with the strongest other participant using max/second-max logic • B. Password – finding the longest substring that is both prefix and suffix and also appears in the middle (string pattern problem using prefix-function/KMP idea) • Practicing competitive programming style implementation with multiple test cases and constraints The Password problem was particularly interesting because it connects string-matching concepts with prefix–suffix patterns. The more patterns you see, the faster new problems start to look familiar. 🔁 #75DaysOfStriverA2Z #StriverA2ZDSA #DSA #Codeforces #CompetitiveProgramming #CodingJourney #Consistency

🚀 Just solved LeetCode 3643 - Reverse Submatrix Today I worked on a really interesting matrix manipulation problem where the goal was to reverse a k×k submatrix efficiently. 💡 Key Insight: Instead of using extra space, I applied a two-pointer approach to swap rows from top to bottom — making the solution clean and optimal. ⚡ What I learned: • In-place matrix transformations • How to optimize nested loops • Importance of visualizing row/column operations 🧠 Complexity: Time → O(k²) Space → O(1) 📌 Small problems like this build strong fundamentals for bigger DSA challenges! 💻 Code + Explanation PPT available on my GitHub 👇 #LeetCode #DSA #CodingJourney #CPlusPlus #ProblemSolving #Tech #Programming #100DaysOfCode

Bitfields in C be like: “Let’s save memory,” they said. “Just pack everything into bits,” they said. Meanwhile: 1 bit → flag 3 bits → status 5 bits → mood swings of the code And debugging? Congratulations 🎉 You’re now decoding binary emotions instead of logic. Efficient? Yes. Readable? Depends on how much coffee you had ☕ #EmbeddedSystems #CProgramming #Bitfields #LowLevelProgramming #DebuggingLife

Multithreading in theory vs reality 🧵⚙️ In theory: Every thread executes independently, efficiently, and peacefully. In reality: Race conditions, deadlocks, and thread competition, context switching, synchronization issues etc. 👉 Writing multithreaded code is easy. 👉 Writing correct multithreaded code is the real challenge. #Multithreading #Programming #SoftwareEngineering #BackendDevelopment #CPP #CppProgramming #ModernCPP #Multithreading #Concurrency #ParallelProgramming #SystemProgramming #SoftwareEngineering #CodingLife

Clean code starts with mastering the basics. In this small C++ example, I implemented two simple but important functions: • SumArray to calculate the total sum of array elements • ArrayAverage to compute the average using the sum function and proper type casting A good reminder that strong software engineering is built on clear logic, reusable functions, and well-documented code.
