Can you help me with this homework, I attached the picture.

## 2. The `findStr` Function
Implement your version of the standard C-library function `strstr()`. To avoid conflicts with names in the standard library, use `findStr()`.
```c
const char * findStr(const char *s1, const char *s2);
```
The `findStr` prototype.
### The function:
- Finds the **first occurrence** of the entire string `s2` inside the string `s1`.
- Returns a pointer to the first occurrence.
- If no match is found, then return the C++ `nullptr`.
- If `s2` points to a string of zero length, then return `s1`.
### Here are some examples:
```c
findStr("cowtown", "ow"); // returns &s1[1]
findStr("cowtown", "own"); // returns &s1[4]
findStr("cowtown", "two"); // returns nullptr
```
Using the `findStr` function.
### Note
You may use pointer notation or array notation. However, **do not use any functions from the standard library**. That includes `strlen()` or the C++ `string` class.
