Circular Array Rotation in JavaScript | Rotate Array by K Positions (No Built-in Methods)
In this video, we implement circular array rotation in JavaScript by rotating an array to the right by K positions, without using any built-in methods.
You will learn:
What circular rotation is
How to rotate an array manually using loops
Time and space complexity of the solution
Common interview use cases
Example Output:
Input: [1, 2, 3, 4, 5], K = 2
Output: [4, 5, 1, 2, 3]
