Question
The mode of a dataset is the item that appears most frequently.

Write a program to read in numbers between 1 and 100 and then report the mode. If more than one number appears most frequently, choose the highest number.

**The most frequent value was 42, appearing 9 times.**

### Code Explanation:

```cpp
#include <iostream>

using namespace std;

int main() {
    // TODO: Write your code here

    cout << "The most frequent value was " << 50 << ", appearing " << 0 << " times." << endl;
}
```

This C++ code snippet is a template for finding the mode of a dataset consisting of numbers between 1 and 100. 

- The `#include <iostream>` directive allows the program to use input and output streams, such as `cout`.
- The `using namespace std;` line enables the use of standard functions and objects without specifying the `std::` prefix.
- The `main()` function contains a `TODO` comment, indicating where to implement the logic for reading the numbers and finding the mode.
- The `cout` statement is currently hardcoded to display that the most frequent value was 50, appearing 0 times, serving as a placeholder for when the actual logic is written.

To complete the task, you will need to implement the logic for reading inputs, counting frequencies, determining the mode, and updating the `cout` statement with the appropriate values.

### Tutorial: Rotating a 4x4 Text Drawing 90 Degrees Right

In this tutorial, we will develop a program that can read a 4x4 text drawing consisting of capital letters A-Z and rotate it 90 degrees to the right.

#### Input and Output Example

**Input Drawing:**
```
I I I I
. I I .
. I I .
I I I I
```

**Output Drawing:**
```
I . . I
I I I I
I I I I
I . . I
```

#### Task Overview

The task is to create a program that reads the input drawing and transforms it into the rotated version, as shown above.

#### Code Template

Below is the template to get you started. Fill in your code where indicated:

```cpp
#include <iostream>
using namespace std;

int main() {
    // TODO: Write your program here
}
```

- The program should be able to read a 4x4 grid of characters and output the rotated version of it.
- Ensure that the program handles the rotation correctly to produce the desired output.

By completing this task, you will improve your understanding of manipulating 2D arrays in C++.
