Leetcode 3335. Total Characters in String After Transformations I | Python Deque Rotation Trick 🔁

In this video, we tackle Leetcode 3335: "Total Characters in String After Transformations I" using Python's deque for efficient rotations and frequency manipulation.

We start with a character frequency array, rotate it over multiple transformations, and show how the final sum is computed.

This tutorial breaks down the core logic, gives you dry runs, and teaches important Python tricks with ord(), deque, and modulo operations.

📌 What You’ll Learn:

How to represent string frequencies with arrays
Why deque is ideal for cyclic rotation
Modulo operations to handle large integers
Efficient simulation of transformations
Python tricks for Leetcode success

🧠 Difficulty: Medium
🛠 Languages: Python
🔥 Great for: Competitive coders, Leetcode learners, Python enthusiasts
