In this video, you'll learn how to solve a complex string manipulation problem in C++. Alice and Bob play a game where they modify a string based on two operations:
Append the current string to itself.
Append a modified version where each character is shifted to the next character in the alphabet.
The goal is to find the *k-th character* after applying all the operations. This problem involves string expansion, character transformation, and reverse simulation.
📌 Topics Covered:
Efficient handling of large `k` (up to 1e14)
Reverse operation tracking
Character manipulation logic in C++
🧮 Example:
```
Input:
k = 10
operations = [0,1,0,1]
Output:
b
```
📚 This is a great problem for mastering string processing in C++ and improving your problem-solving skills for coding interviews.
