Day 59 of my #100DaysOfCode challenge 🚀 Today I implemented a Python program to count the number of set bits (1s) in a binary number. This uses an efficient bit manipulation technique and is very important in DSA & low-level optimization. What the program does: • Takes an integer n as input • Converts it conceptually to binary • Counts the number of set bits (1s) • Uses an optimized approach instead of checking each bit Example Outputs: 29 (11101) → 4 set bits 7 (111) → 3 set bits 16 (10000) → 1 set bit How the logic works: Uses Brian Kernighan’s Algorithm: n = n & (n - 1) • This removes the rightmost set bit in each step • Repeat until n = 0 • Count how many times this operation runs Why this is important: – Much faster than checking every bit ⚡ – Used in: Bit manipulation problems Competitive programming Low-level optimizations – Common in coding interviews Time Complexity: O(number of set bits) Space Complexity: O(1) Key Takeaways: – Understanding bitwise operations – Efficient counting techniques – Writing optimized solutions – Learning real-world low-level logic #100DaysOfCode #Day59 #Python #Programming #DSA #Algorithms #BitManipulation #Binary #CodingPractice #ProblemSolving #InterviewPrep #Optimization #DeveloperJourney #Consistency #BTech #CSE #AIandML #VITBhopal #TechJourney

Day 58 of my #100DaysOfCode challenge 🚀 Today I implemented a Python program to generate prime numbers within a given range. This is a practical extension of prime checking and useful in many DSA and real-world problems. What the program does: • Takes a range (start, end) as input • Checks each number in the range • Identifies whether it is prime or not • Returns a list of all prime numbers in that range Example Output: Prime numbers between 1 and 50: [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47] How the logic works: Start from max(2, start) For each number: • Assume it is prime • Check divisibility from 2 → √n If divisible → not prime If not divisible → add to result list 👉 Uses square root optimization for better performance Why this is important: – Builds on prime number fundamentals – Useful in: Competitive programming Number theory problems Range-based queries – Helps understand optimization using √n Time Complexity: O(n√n) Space Complexity: O(k) (number of primes) Key Takeaways: – Applying optimized prime checking – Working with ranges and loops – Improving efficiency using √n – Writing clean and scalable code #100DaysOfCode #Day58 #Python #Programming #DSA #Algorithms #PrimeNumbers #NumberTheory #CodingPractice #ProblemSolving #InterviewPrep #Optimization #DeveloperJourney #Consistency #BTech #CSE #AIandML #VITBhopal #TechJourney

🚀 Day 3 of My 30-Day Python Journey Today’s focus was on building decision-making logic a key step toward writing intelligent programs. 🔹 What I covered today: • Conditional statements: if, elif, else • Handling multiple conditions and nested logic • Using logical operators to refine decisions • Writing small programs based on real-world scenarios 💡 Key Takeaway: Code becomes powerful when it can make decisions. Conditional logic is what transforms static scripts into dynamic, responsive programs. 🧪 Practice Focus: Worked on mini tasks like number checking (positive/negative), even/odd detection, simple login validation, and finding the largest of three numbers. 📌 Next Step: Exploring loops to automate repetitive tasks and make programs more efficient. Step by step, building both logic and consistency. 💻 #Python #CodingJourney #LearnToCode #Developers #Programming #TechGrowth #100DaysOfCode

54/75 Today I spent some time learning about asynchronous programming in Python and honestly, it changed how I think about performance. Instead of waiting for one task to finish before starting another, async lets your code handle multiple things at once. It’s especially powerful for I/O-heavy tasks like API calls, database queries, or web scraping. What stood out to me: • Faster execution without adding more hardware • Cleaner handling of concurrent operations • The power of async and await when used correctly It’s one of those concepts that feels confusing at first, but once it clicks, you start seeing so many real-world use cases. Still experimenting with it but definitely a step forward in writing more efficient systems 🚀 #Python #AsyncProgramming #LearningInPublic #SoftwareDevelopment

Day 26/100: Writing Cleaner, Faster, and Pythonic Code! Today was all about efficiency and elegance. I dived deep into Comprehensions—one of Python’s most powerful features for creating new sequences from existing ones. Key Technical Takeaways: List Comprehension: Reducing multi-line for loops into a single, readable line. [new_item for item in list if test] Dictionary Comprehension: Creating complex mappings and filtering data on the fly. Conditionals in Comprehensions: Mastering how to use if and if-else inside a single line of code. Project: NATO Alphabet Converter: Developed a tool that takes any word and converts it into its NATO phonetic code (Alpha, Bravo, Charlie...) using dictionary comprehension. My code is becoming significantly shorter, more readable, and much more efficient. It’s amazing how a simple shift in syntax can make such a big difference in software quality! Check out my NATO Alphabet project here: https://lnkd.in/gZ2bdXua #Python #CleanCode #100DaysOfCode #Pythonic #SoftwareDevelopment #CodingEfficiency #VSCode

In my previous post, i talked about breaking code with one small change. This time? It gets worse. You write the code. 1 error. You fix the error. 12 new errors. And your screen is basically on fire. Every programmer has been here. Every single one. Here is the truth about errors in coding: Errors are not failure. They are feedback. Python does not hate you. It is telling you exactly what is wrong. Fixing one error exposing others means you are making progress. The code was always broken. Now you can finally see it. How to handle cascading errors like a professional: Fix from the top. The first error often causes all the others. Read the full error message. The answer is always in there. Do not fix everything at once. One error at a time. Take a break. Fresh eyes fix bugs faster than tired ones. Note: Debugging is not the obstacle. It is the job. #Python #Debugging #DataScience #LearnToCode #BeginnerCoder #Coding #StudentLife
