Day 29/40🚀. I was meant to post this yesterday but I forgot 😭. I learnt to use the passive buzzer(it's quite different from the active buzzer). I integrated it with a potentiometer. #40daysofcode #Arduino

Day 26/40🚀. I continued implementing the little functions I have learnt in Arduino, building micro projects. I learnt how to read from the serial monitor, how to write from the serial monitor and how to use the while loop. #40daysofcode #Arduino

🧵 DAY 10/40 – #DSA40 🧠 Topic: String Parsing & Pattern Search Solved today: 🔹 Leetcode #8 – String to Integer (atoi) 🔹 Leetcode #28 – Find Index of First Occurrence in String #Python #40DaysOfCode #LeetCode 👇 Let’s break down the logic!

Day 12 of #40DaysOfCode: Learned array methods; now exploring Numbers, Dates, Internationalization, and Timers. #BuildInPublic #CodeNewbie #Programming #Coding #TechTwitter #LearnToCode #100DaysOfCode #SoftwareEngineering #JavaScript #AdvancedJS #DevCommunity

Hey everyone 👋 For the next 40 days, I’ll be learning and sharing my progress on Python + Machine Learning — one day, one lesson, one post. 💡 Why? Because consistency beats motivation. 🎯 Goal: Build strong foundations in Python, data handling, and ML basics.

Day 4/40 of Python -ML Today I explored while loops — how to keep programs running until a condition is met. I learned about using flags, break and continue, avoiding infinite loops, and looping through lists and dictionaries. It’s amazing learning new things ... #PythonML

Day 5/40 of my Python-ML journey Today was all about functions... Learned how to write and use functions — defining, passing info, returning values, default parameters and keeping code clean & reusable. Feeling more confident with each line I write 💪 #PythonMl #40DaysOfCode

🧵 DAY 19/40 – #DSA40 🧠 Topic: Linked List – Cycles & Rotation Today’s grind: 🔹 Leetcode #142 – Linked List Cycle II 🔹 Leetcode #61 – Rotate List Let’s unpack the tricks & patterns 👇 #40DaysOfCode #Leetcode #DSA #Python

🧵 DAY 20/40 – #DSA40 🧠 Topic: Linked List – Reordering & Dividing Today’s grind: 🔹 Leetcode #143 – Reorder List 🔹 Leetcode #725 – Split Linked List in Parts Let’s break it down 👇 #40DaysOfCode #Leetcode #DSA #Python

🧩 Leetcode #725 – Split Linked List in Parts 🎯 Goal: Divide a list into k equal(ish) parts Steps: ➤ Count total nodes ➤ Distribute base size & extras ➤ Walk and split accordingly 💡 Smart chunking logic without extra space!

📌 Takeaways (Day 20) ✅ Reorder List: → Find mid → Reverse second half → Merge like a zipper 🪡 ✅ Split List in Parts: → Count nodes → Divide into k parts → Extra nodes go to earlier parts #DSA #40DaysOfCode #Leetcode #LinkedList #CodingTips

Day 9 of #40DaysOfCode: Completed the mini challenge. #BuildInPublic #CodeNewbie #Programming #Coding #TechTwitter #LearnToCode #100DaysOfCode #SoftwareEngineering #JavaScript #AdvancedJS #DevCommunity

🧵 DAY 11/40 – #DSA40 🧠 Topic: Binary Search – Classic & Insertions Today’s grind: 🔹 Leetcode #704 – Binary Search 🔹 Leetcode #35 – Search Insert Position Let’s break down the core logic and tricks 👇 #BinarySearch #Python #LearnInPublic

📌 Leetcode #35 – Search Insert Position 🎯 Goal: Return index to insert target in sorted array. Approach: Binary search just like #704. If target not found, start ends up at the right insert point. 💡 Trick: Final return is start — that’s where it belongs.

🎯 Takeaways ✅ Binary search cuts time from O(n) → O(log n) ✅ Perfect for sorted arrays ✅ Watch edge cases: insertion at 0 or end of array 📅 Tomorrow: Rotated Binary + Range Search #40DaysOfCode #DSAChallenge #PythonTips #DevCommunity #LeetCode

Day 10 of #40DaysOfCode: Learned React. #BuildInPublic #CodeNewbie #Programming #Coding #TechTwitter #LearnToCode #100DaysOfCode #SoftwareEngineering #JavaScript #AdvancedJS #DevCommunity

Day 25/40🚀. I'm back with update on my Arduino lessons. I worked on a light dimmer using potentiometer. I also learnt to use if statement and for loop in C++. #40daysofcode #Arduino

🧵 DAY 18/40 – #DSA40 🧠 Topic: Cycle Detection (Floyd’s Algorithm) Today’s Leetcode grind: 🔹 #141 – Linked List Cycle 🔹 #287 – Find the Duplicate Number Let’s break it down 👇 #LinkedList #FloydsAlgorithm #Leetcode #DSA #Python

🎯 Leetcode #287 – Find the Duplicate Number 🧩 Goal: Find the one duplicate number in an array of n+1 integers. ⚙️ Approach: ➤ Think of array as a linked list → nums[i] is a pointer ➤ Apply Floyd’s algo to find the cycle start = duplicate number!

🎯 Takeaways ✅ Linked lists & arrays can both form cycles ✅ Floyd’s algo works beyond just classic loops ✅ Elegant pointer tricks = low memory, fast runtime! 📅 Tomorrow: Detect & locate cycle entry (Linked List Cycle II) #40DaysOfCode #DSAChallenge #Leetcode #Python

Day 13 of #40DaysOfCode: Don't forget to follow me guys 💪💪💪 #BuildInPublic #CodeNewbie #Programming #Coding #TechTwitter #LearnToCode #100DaysOfCode #SoftwareEngineering #JavaScript #AdvancedJS #DevCommunity

Day 6 of #40DaysOfCode Reinforcing my knowledge of array methods. #BuildInPublic #CodeNewbie #Programming #Coding #TechTwitter #LearnToCode #100DaysOfCode #SoftwareEngineering #JavaScript #AdvancedJS #DevCommunity

🧗 Leetcode #70 – Climbing Stairs 🎯 Goal: Count ways to climb to the nth stair (1 or 2 steps at a time). 🔁 Formula: ways(n) = ways(n-1) + ways(n-2) 💡 Classic recursion with overlapping subproblems (DP comes later 😉) #Recursion #DSA

✅ Takeaways: Recursion = base case + self call Binary recursion = divide problem into halves Many real-world problems follow Fibonacci structure 📅 Tomorrow: Subsets & Backtracking 🔥 Let's Connect for updates! #40DaysOfCode #Python #Leetcode #Recursion #DSA

Day 40 🚀. My 40 day journey comes to an end today. It really has been a interesting journey. I spent most of my day away from home, but it didn't hinder me learning. I learnt to use the 4digits7segment module. It was quite challenging and it took me time to debug #40daysofcode

Day 19 of #40DaysOfCode: Operation with Dates 💪, unto internationalization😉 #BuildInPublic #CodeNewbie #Programming #Coding #TechTwitter #LearnToCode #100DaysOfCode #SoftwareEngineering #JavaScript #AdvancedJS #DevCommunity
