#Day12 of #100DaysOfCode ! DSA : Revision + pointers & address concepts in deep. MongoDB : Date + Array + Type operators. #DSA #DevCommunity #CodingJourney #MongoDB
#Day11 of #100DaysOfCode 🚀 📚 DSA: Solved Merge Two Sorted Lists & Remove Nth Node from End 🔥 🗄️ MongoDB: Learned String & Arithmetic operators 💡 ❓Which do you find trickier — Linked List problems or MongoDB queries? #CodingJourney #DSA #MongoDB #DevCommunity #rasprogrammer

#Day10 of #100DaysOfCode ! DSA : Reverse linked list, Palindrome Linked list using array approach problems solved MongoDB : Revise previous concepts #CodingJourney #dsa #MongoDB #leetcode #rasprogrammer
#Day9 of #100DaysOfCode ! DSA: Basics of Linkedlist. MongoDB: $lookup(join), $bucket . #CodingJourney #DSA #MongoDB #DevCommunity #Linkedlist #rasprogrammer
#Day8 of #100DaysOfCode ! DSA: skipped today. MongoDB: Aggregation Operator. #CodingJourney #DSA #MongoDB #DevCommunity
#Day7 of #100DaysOfCode 🚀 📚 DSA: Revised Unique Paths + solved Rat in a Maze 🐀 🗄️ MongoDB: Query operators revision + findOneAndUpdate vs findOne ❓Do you revise old concepts daily or dive into new ones? #CodingJourney #DSA #MongoDB #DevCommunity #GFG #LeetCode

#Day6 of #100DaysOfCode 🚀 📷 DSA: Cracked Unique Paths using recursion! 🔍 MongoDB: Skipped today. ❓What’s your favorite approach — recursion or DP? #CodingJourney #DSA #DevCommunity #MongoDB

#Day5 of #100DaysOfCode ! Did nothing 😔Why am I not consistent ? 📷#Coding #CodingJurney #Mongodb #DSA #DevCommunity
#Day4 of #100DaysOfCode ! Do nothing 😔 Why am I not consistent ? 😔😔 #Coding #CodingJurney #Mongodb #DSA #DevCommunity
#Day3 of #100DaysOfCode ! 🔍 MongoDB: comparison, logical & element query operators. ⚡ DSA: solved Pow(x, n). 💻 Software build: nil today, grind never stops! 🔥 Onwards & upwards! 👉 Devs, which MongoDB operator do you use the most? 👇 #CodingJourney #MongoDB #DSA #DevCommunity

#Day2 of #100DaysOfCode! 📚 MongoDB CRUD (DB & Collections). 🤯 DSA: subsets vs subsequences (recursion concept without coding but try to dry run). 🔥 Steady grind! #CodingJourney #MongoDB #DSA
#Day1 of #100DaysOfCode! 🚀 Crushed it with Permutations & Combinations + LeetCode's Unique Paths III. 💻 Hyped to level up my coding game! 🔥 Ideas for Day 2? #CodingJourney #LeetCode
I'm accepting and starting #100DaysOfCode challenge from today. #DSA #LeetCode #Javascript
Problem: Generate all unique permutations of an array. Approach: Backtracking + duplicate check using result storage. Language: C++ Time: O(n * (n!)^2) (inefficient due to duplicate checking) #DSA #100DaysOfCode #LeetCode #DevCommunity

Today I deep-dived into SOLID principles 💡 Clean code isn’t just about syntax—it’s about design. S - Single Responsibility O - Open/Closed L - Liskov Substitution I - Interface Segregation D - Dependency Inversion Next step → applying them in real projects 🚀 #SOLID #CleanCode
