Find the Largest Element in an Array | Python DSA for Beginners (2 Easy Approaches)
In this video, you’ll learn how to find the largest element in an array using Python.
We’ll walk through two beginner-friendly approaches with step-by-step explanations:
🔹 Approach 1: Sort the array and return the last element
🔹 Approach 2: Find the maximum value in a single pass — an efficient method used in real-world scenarios
👨💻 What You’ll Learn:
How to use Python’s built-in sort() method
How to scan an array and track the maximum element
Step-by-step dry run of logic with comparisons
Time and space complexity analysis for each approach
📌 Example Used: Input array: [3, 7, 5, 9, 4]
Output: 9
✅ Time Complexities:
Sorting approach: O(n log n)
Single pass approach: O(n)
where n is length of array
