Solved LeetCode 1611: Minimum Bit Operations to Zero with Python

🧠 Day 38 / 100 – Recursion: Factorial of a Number (LeetCode-#509) Today’s challenge was all about recursion — one of the most elegant concepts in programming. I revisited the Factorial problem, which beautifully demonstrates how a big problem can be broken into smaller subproblems. The idea is simple: 👉 The factorial of n is n * factorial(n-1) until n becomes 1. But the real challenge lies in understanding the flow of recursive calls and how the call stack unwinds to give the final result. This problem reminded me that recursion isn’t just about repeating a function — it’s about trusting the process and thinking in terms of smaller steps to solve complex problems. 🔍 Key Learnings Every recursive function must have a base case to prevent infinite loops. The call stack stores each recursive call until it’s resolved. Recursion is a natural fit for problems that can be divided into smaller, similar subproblems. 💭 Thought of the Day Recursion teaches patience and structure. Sometimes, you need to trust that solving the smaller version of a problem will help you conquer the big one — both in code and in life 💫. 🔗 Reference Problem:https://lnkd.in/g3yNGDbJ #100DaysOfCode #Day38 #LeetCode #Python #Recursion #Factorial #ProblemSolving #CodingChallenge #Algorithms #ProgrammingMindset #DataStructures #CleanCode #LearnByDoing #TechGrowth #PythonProgramming

⏳ Leetcode #1611: Minimum One Bit Operations to Make Integers Zero 🔍 Today I picked up a problem that looked chaotic at first: transforming any integer into zero using very restricted bit-flip rules. Every bit could only flip if the bits below it satisfied certain conditions, making the process feel unpredictable 🧩. But once I dug deeper, something interesting appeared. The pattern wasn’t random at all; it was secretly following Gray Code. That realization turned a confusing sequence of operations into a clean, structured transformation ✨. ✅ Key Insight: The number of operations directly aligns with converting a Gray-Code-like representation of n into its binary form. ✅ Time Complexity: O(log n) ✅ Space Complexity: O(1) These are the moments that make problem solving rewarding: when the “why is this so messy?” suddenly becomes “this is actually lowkey clean” 🧠💡. #DataStructures #LeetCode #CodingChallenge #ProblemSolving #Python #DSA #ComputerScience #learningEveyDay

🚀Day 71 of #100DaysOfCode Today's challenge was LeetCode Problem #3228 - Maximum Number of Operations to Move Ones to the End. This problem focused on binary string manipulation and calculating the maximum possible operations under specific conditions. It tested the ability to analyze how '1's can be shifted past '0's efficiently while maintaining optimal time complexity. Key Learnings: Applied an efficient linear approach to avoid unnecessary simulations. Learned to track and update the count of '1's dynamically during iteration. Strengthened problem-solving strategies for string-based algorithmic questions. Language Used: Python Runtime: 55 ms (Beats 74.85%) Memory: 18.12 MB (Beats 54.49%) Day 70 represents continuous progress in improving logical reasoning and coding efficiency. Each solved problem builds a stronger foundation for advanced algorithmic thinking and real-world software development. #LeetCode #Python #ProblemSolving #CodingChallenge #100DaysOfCode #Algorithm #DataStructures #Mythyly

✅Day 55 of #100DaysOfCode Solved LeetCode 3346 — Maximum Frequency of an Element After Performing Operations I (Accepted ✅ 635/635 cases) Thrilled to share I got an Accepted solution in Python — runtime: 289 ms (beats ~92%) and memory: 30 MB (beats ~95%) 🎉 What I did: • Sorted the array and used a sliding-window (two pointers) approach. • Kept a running sum of the window to compute how many operations are needed to make all elements equal to the current right-end value. • Grew the window while remaining within numOperations, otherwise moved the left pointer — the maximum window size is the answer. Why this works: sorting groups close values together, and the sliding window + prefix-sum-like maintenance lets us calculate required increments efficiently (O(n log n) for the sort, O(n) for the scan). Key takeaways: • Classic use of sort + two-pointer for "make equal with limited ops" problems. • Keep aggregate information (like sum) to avoid recomputing costs inside the window. • Small optimizations in Python (use integers, avoid heavy operations inside loops) help pass tight constraints. If you want, I can share the final Python snippet or a short walkthrough of the logic.

🚀 Day 91/100 of the #100DaysOfCode Challenge! #Day91 of #100Dayscodingchallenge:The journey continues, and today's focus was on strengthening my core Python skills by tackling fundamental problems using for loops. It's amazing how these building blocks can solve such a variety of challenges. Here’s a look at what I practiced: ✔️ Palindrome Checker: Wrote a function to determine if a word reads the same forwards and backwards, reinforcing string manipulation and loop control. ✔️ Remove Vowels: Created a script to filter all vowels out of a given sentence, a great exercise in string iteration and conditional checks. ✔️ First Part or Last Part: Solved a problem to extract and compare segments of a string, honing skills in string slicing and loop logic. ✔️ Character Identifier: Built a program to classify a character as a Letter, Digit, or Special Character, diving into Python's built-in methods (isalpha(), isdigit()). Tackling these problems was a fantastic reminder that a solid grasp of fundamentals like for loops is crucial for writing efficient and clean code.

🐍Python Day 3 Each day, the logic gets tougher, but so does my clarity. 🔹 What I Tried: I wanted to take yesterday’s logic and make it work across multiple numbers instead of just one. 🔹 What I Built: A Python program that: ✅ Generates numbers within a range ✅ Checks if they’re even, odd, positive, or negative ✅ Detects prime numbers efficiently using the √n trick 🔹 What I Learned: Even a small piece of code can teach how to think systematically — to break a big problem into smaller parts and optimize as you go. Coding truly shapes how you feel, not just what you type. 🔹 What Was Challenging: Getting the prime number logic right without unnecessary loops. It took a few test runs (and print statements), but it finally clicked. Each day, a new script. Each script is a new insight.

🔁 Day 45 of #100DaysOfDSA — Reverse Linked List Problem: Reverse Linked List (LeetCode #206) Given the head of a singly linked list, reverse it and return the reversed list. Concepts Used: 🧠 Stack-based approach Traverse the linked list and push each node’s value into a stack. Then reassign values by popping from the stack to reverse the list. 🧩 Learning Reflection: This problem helped me understand how stacks can simplify linked list manipulations. Though not the most space-efficient solution, it reinforces the concept of LIFO (Last In, First Out) operations beautifully. ⏱️ Complexity: Time: O(N) Space: O(N) 💬 Closing Thought: Sometimes, using an extra data structure makes logic clearer — and that’s okay while learning. #LeetCode #DSA #LinkedList #Python #100DaysOfCode #CodingJourney

Day 31 / 100 – Add Strings (LeetCode #415) Today’s challenge was all about simulating manual addition without using any built-in integer conversions. Given two numbers as strings, the task was to return their sum — also as a string. This problem really emphasized the importance of breaking problems into small, logical steps rather than relying on shortcuts. 🔍 Key Learnings Recreated the digit-by-digit addition process using ASCII values. Practiced handling carry-over efficiently while iterating backward. Strengthened my understanding of string manipulation and arithmetic logic. 💭 Thought of the Day True problem-solving isn’t about using built-ins — it’s about understanding how things work underneath. Today reminded me that mastery grows when we rebuild the basics from scratch, not when we avoid them. 🔗 Problem Link: https://lnkd.in/gHMt9vj9 #100DaysOfCode #Day31 #LeetCode #Python #ProblemSolving #StringManipulation #Algorithms #DataStructures #CodingChallenge #CodeEveryday #TechGrowth #LearningJourney
