Design and Analysis of Algorithm (DAA) Unit-1 | Lec-6 Selection Sort Algorithm | B.Tech CSE/IT

Welcome to Lecture-6 of Design and Analysis of Algorithm (DAA) – Unit 1 for B.Tech students. In this lecture, we will learn the Selection Sort Algorithm from scratch in a simple, beginner-friendly, and exam-oriented way. We will understand how Selection Sort works, its step-by-step algorithm, and why it repeatedly selects the smallest element from the unsorted part of the array and places it at the correct position. This lecture also includes a complete dry run on an example array, detailed analysis of the algorithm based on different criteria, and the complete Java implementation with line-by-line explanation. Whether you are preparing for B.Tech (BCS-503), university exams, placements, or coding interviews, this lecture will help you build a strong foundation in Design and Analysis of Algorithms (DAA). 📖 Topics Covered in this Lecture ✅ What is Selection Sort Algorithm? ✅ How Selection Sort Works ✅ Sorted Part vs Unsorted Part ✅ Step-by-Step Selection Sort Algorithm ✅ Dry Run with Example ✅ Selection Sort Time Complexity ✅ Selection Sort Space Complexity ✅ Stability of Selection Sort ✅ Adaptivity of Selection Sort ✅ Recursive vs Non-Recursive Selection Sort ✅ Selection Sort Java Program ✅ Selection Sort Code Explanation ✅ Exam-Oriented Notes 🎯 This Lecture is Useful For ✔ B.Tech (CSE / IT) ✔ AKTU Students ✔ BCA Students ✔ MCA Students ✔ DAA (Design and Analysis of Algorithms) ✔ Data Structures and Algorithms (DSA) ✔ Java Programming ✔ Semester Examination Preparation ✔ Coding Interview Preparation ✔ Beginners Learning Sorting Algorithms 💻 Java Program Covered ✔ Selection Sort Program in Java ✔ Complete Code Explanation ✔ Dry Run of the Program ✔ Logic Behind Every Loop ✔ Output Explanation 📌 Previous Lecture Bubble Sort Algorithm – Easy Explanation with Code 📌 Next Lecture Insertion Sort Algorithm – Easy Explanation with Code 📥 Free Notes are provided along with this lecture to help you revise quickly before your exams.
