"Rotate Array by K Positions in Python | LeetCode 189 Solution | FAANG Interview Prep | DSA"

Description:
In this video, we tackle the LeetCode 189 - Rotate Array problem in Python. We demonstrate how to efficiently rotate an array to the right by k positions (or k elements) and cover multiple methods to solve it, including the in-place solution. This problem is frequently asked in FAANG interviews and is a crucial part of Data Structures and Algorithms (DSA) preparation.

We will walk through rotating the array by k positions, focusing on solving it with O(n) time complexity and O(1) space. Whether you are solving the problem in Java, Python, C++, JavaScript, or GFG, the core concept remains the same, and we will explore how to apply it in these languages too.

Key Concepts:
Rotate the array by k positions, rotating it to the right (e.g., rotate array to the right).
We’ll discuss rotating an array by k elements and k positions, comparing approaches for different languages, such as rotate array in Python, rotate array in Java, rotate array in C++, and rotate array in JavaScript.
Explore solutions like block swap algorithm for rotating the array efficiently.
Learn how to rotate the array by d places or by one position as well.
Understand the rotation in different directions: rotate array to left vs. rotate array to right.
Example:
Input: [1, 2, 3, 4, 5, 6, 7], k = 3 → Output: [5, 6, 7, 1, 2, 3, 4]
Input: [-1, -100, 3, 99], k = 2 → Output: [3, 99, -1, -100]
Whether you're learning about array rotation in Java Tamil or solving the problem in C or JavaScript, this video will give you a comprehensive understanding of how to approach rotate array problems and ace coding interviews.
