DSA Day 3: Linear Search in Array | Find Element & Return Index
Welcome to DSA Day 3! 🚀
In this video, we'll learn how to solve one of the most fundamental DSA problems using the **Search Pattern**.
You'll learn how to:
Check whether an element exists in an array
Return the index of the element if it is found
Think through the problem before writing code
Build the logic step by step using Python
📌 In this video:
✔ Search an element in an array
✔ Return the index of the element
✔ Understand the Traversal + Search Pattern
✔ Dry Run with Examples
✔ Beginner-Friendly Python Explanation
✔ Learn the thought process behind the solution
💡 Why is this important?
The Search Pattern is one of the most reusable DSA patterns. Once you understand it, you'll be able to solve many related problems with confidence.
📝 Homework Challenge:
Try solving these problems using the same Search Pattern:
🔹 Find the First Occurrence of an Element
🔹 Find the Last Occurrence of an Element
🔹 Count the Occurrences of an Element
Pause the video, think about the logic, and try solving them on your own before watching the next video.
Remember:
*Don't memorize solutions. Learn the pattern and train your thinking.*
