Delete Node in Linked List Tutorial

🚀 Day 93 of #100DaysOfCode Challenge Today’s problem was all about identifying “Beautiful Strings” 🔢✨ A numeric string is called beautiful if: ✔️ It can be split into a sequence of increasing numbers ✔️ Each number is exactly +1 from the previous ✔️ No leading zeros allowed 💡 What I Learned Today: How to break strings into valid sequences Handling large numbers using long long Importance of string comparison vs integer operations Edge cases like: Leading zeros ❌ Single digit strings ❌ Invalid increments ❌ 🧠 Approach: Try all possible starting numbers Generate the sequence dynamically (x, x+1, x+2…) Match the built string with the original If matched → ✅ YES x Else → ❌ NO 💻 Example: 👉 Input: 91011 👉 Output: YES 9 ⚡ Key Takeaway: Sometimes brute force with smart validation is the best approach! 📅 Consistency is the real game changer.

Underlying data structures used in STL:- It explicitly maps: vector → dynamic array array → static array deque → segmented array list → doubly linked list forward_list → singly linked list map/set family → red-black tree unordered_map → hash table priority_queue → heap #cpp #softwareengineering #embedded #systemdesign #designpatterns #programming #cleanarchitecture #cplusplus #embeddedsoftware #coding

In LeetCode 867 – Transpose Matrix Today I worked on a basic but important matrix problem: transposing a matrix. The idea is simple — convert rows into columns. Understanding matrix traversal helps build a strong foundation for more complex problems. #LeetCode #DSA #Coding #Programming #ProblemSolving #100DaysOfCode #DeveloperJourney #CodeNewbie #Tech #Learning #CodingLife #ComputerScience #Algorithms #Matrix #Consistency

Flatten Binary tree to linked list Approach: Do kind of post-order traversal ( right -> left -> root ) maintain a previous node go right (recursively) go left (recursively) make root->right point to previous and root->left point to null and update previous to root TC: O(N) SC: O(N) - recursive stack #DSA #programming #coding #buildinpublic #Technology #ProblemSolving #LeetCode #LearnInPublic  #Consistency

Solved LeetCode 151: Reverse Words in a String Today, I worked on reversing the order of words in a string while handling extra spaces efficiently. I learned how to: Remove leading, trailing, and multiple spaces Extract words correctly Reverse their order using clean logic and STL I implemented an optimized solution with: Time Complexity: O(n) Space Complexity: O(n) This problem helped me improve my understanding of string manipulation, edge case handling, and clean coding practices https://lnkd.in/getBKFiE GitHub Repo: https://lnkd.in/gg4daDpn #day18 #DSA #Cpp #LeetCode #Coding #Programming #Learning #ProblemSolving #Strings

Leetcode daily - Day 3 🧠 Problem: (Isomorphic Strings) Check if two strings are isomorphic (one-to-one character mapping with order preserved). 💡 Approach: Used two hash maps to maintain mapping: s → t t → s If any mismatch occurs → return false, else true. 🔑 Key Learning: One-to-one mapping (bijection) HashMap usage in strings ⏱ Time Complexity : O(n) 💾 Space Complexity : O(1) ✨ Consistency is the key to mastering DSA! #LeetCode #DSA #CodingJourney #ProblemSolving #Consistency #Programming

Mastering the Basics: Linked List in Data Structures Understanding how data is organized is key to becoming a great developer. A Linked List is one of the most fundamental concepts in Data Structures that teaches dynamic memory handling and efficient data flow. Key Takeaways: Each node contains data + pointer to the next node Elements are not stored in contiguous memory Efficient for insertions and deletions compared to arrays Ends with a NULL pointer, marking the end of the list Grasping concepts like Linked Lists builds the foundation for advanced topics and real-world problem solving. #DataStructures #LinkedList #DSA #Programming #Coding #SoftwareEngineering #TechLearning #Developers #ComputerScience #CodingJourney #LearnToCode #TechSkil

Solved LeetCode: Power of Two using Bit Manipulation Learned how to efficiently check whether a number is a power of 2 using binary properties. A number is a power of two if it has only one set bit in its binary representation. Used the trick: n > 0 && (n & (n - 1)) == 0 Optimized solution with: Time Complexity: O(1) Space Complexity: O(1) This problem helped me understand bit manipulation, binary concepts, and optimized checking techniques https://lnkd.in/dFdQhMmS GitHub Repo: https://lnkd.in/gg4daDpn #day10 #DSA #Cpp #LeetCode #Coding #Programming #Learning #ProblemSolving #BitManipulation
