Welcome to Day 14 of the Live DSA in C++ & Java by LogicnLearn playlist 🚀
Today’s session covers one of the most fundamental and important topics for coding interviews: ARRAYS.

Arrays are the building block of Data Structures, and mastering them is essential before moving to strings, linked lists, stacks, queues, and advanced DSA topics.

In this session, you will learn Arrays from basics to advanced, with 20+ real coding examples in both C++ and Java. This lecture is extremely useful for interviews, placements, internships, and coding rounds on platforms like GFG, LeetCode, Code360, CodeChef, HackerEarth, and HackerRank.

📘 What You Will Learn Today
🔹 Array Fundamentals

• What is an Array
• Why Arrays are important in DSA & interviews
• Real-life examples of Arrays
• Memory representation of Arrays

🔹 Core Array Concepts

• Types of Arrays (1D & 2D)
• Array traversal techniques
• Insertion and deletion in Arrays
• Searching in Arrays (Linear & Binary Search basics)
• Updating elements
• Time & Space Complexity of Array operations

🔹 Coding Examples in C++ and Java

• Declaring and initializing Arrays
• Traversing Arrays using loops
• Performing insert, delete, and update operations
• Searching elements in Arrays
