feat: Demonstrate String methods endsWith, charAt, startsWith with offset, and character iteration

🧪 Functionality:
1. Check if the string ends with `"Khan"` using `endsWith()`.
2. Fetch character at index `4` using `charAt(4)` — expected output: `'S'`.
3. Check if the substring starting from index 4 starts with `"Shah"` using `startsWith("Shah", 4)`.
4. Print each character of the string using a `for` loop with `charAt(i)`.

🧰 Methods Used:
- `String.endsWith(String suffix)` — checks if the string ends with the specified suffix.
- `String.charAt(int index)` — returns the character at the given index.
- `String.startsWith(String prefix, int offset)` — checks if the string starts with the specified prefix beginning at the given index.
- `String.length()` — gets the total number of characters in the string.

✅ Purpose:
To demonstrate character-wise access and common string checks (start, end, and offset-based prefix) in Java.
