[PART 2] Intermediate Data Structures and Algorithms Introduction: Reaching the Pinnacle of DSA Mastery You’ve navigated through the basics and conquered intermediate concepts. Now, it’s time to dive into the advanced realm of DSA, where optimization...
1. Opposite Direction (Two-pointer from Ends) ✅ Use When: You need to find pairs in a sorted array. You need to check if a string/array is a palindrome. You are finding an optimal solution between two boundaries (like maximum area, min/max sum). ...
When it comes to searching for an element in a sorted array, two popular algorithms often come up: Binary Search and Interpolation Search. While both are efficient compared to linear search, they work in fundamentally different ways. Let’s break them...
Breadth-First Search (BFS) is a fundamental graph traversal algorithm that explores nodes level by level. It is commonly used for finding the shortest path, network broadcasting, and solving various graph-related problems. Understanding BFS BFS start...
[PART - 1] Beginner’s Guide to Data Structures and Algorithms Introduction: Leveling Up Your DSA Knowledge Congratulations! You’ve tackled the basics of DSA. Now it’s time to delve deeper into more complex data structures and algorithms. In this blog...
1. Tree Traversal Techniques Inorder Traversal (Recursive, Iterative) Preorder Traversal (Recursive, Iterative) Postorder Traversal (Recursive, Iterative) Level Order Traversal (BFS Approach) Zigzag Level Order Traversal Boundary Traversal of B...
Introduction of STL What is STL in C++? 🤔 The Standard Template Library (STL) is like the IKEA of C++ programming 🛠️—it gives you all the pieces you need to build complex programs without starting from scratch. Think of it as a magic toolbox where ...
Introduction: Starting Your DSA Journey Data Structures and Algorithms form the backbone of computer science and programming. For anyone venturing into the tech world, a solid understanding of DSA is non-negotiable. It equips you with problem-solving...
Leetcode has more than 3000 DSA questions, but only 10% are really helpful for getting ready for job interviews. If you want to become good at cracking coding interviews, then learn these patterns: 𝟭. 𝗧𝘄𝗼 𝗣𝗼𝗶𝗻𝘁𝗲𝗿𝘀: https://lnkd.in/egfNhP...
Introduction Have you ever wondered how Java’s ArrayList works under the hood? While the standard ArrayList is efficient and easy to use, building your own version from scratch can significantly enhance your understanding of data structures, memory m...
