Stack Implementation using Array | Data Structure and Algorithms

Understanding Arrays in Programming — Simple & Visual Guide An array is one of the most fundamental data structures in programming. It stores multiple values in a single variable using contiguous memory locations, making data access fast and efficient. 📌 Key Concepts Covered: 🧠 Contiguous Memory – Elements are stored next to each other 📏 Fixed Size – Defined at creation time 🧩 Homogeneous Data – Same data type for all elements 🔢 Index-Based Access – Starts from index 0 💡 Example: [10, 20,
