Question

Use C++

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

typedef struct node* NodePtr;

struct node
{
public:
    int data;
    NodePtr link;
};

void print(NodePtr head)
{
    for (NodePtr ptr = head; ptr != NULL; ptr = ptr->link)
        cout << ptr->data << " ";
    cout << endl;
}
```

### Explanation:

This C++ code defines a simple structure and a function to work with a linked list:

1. **Header and Namespace:**
   - `#include <iostream>`: This line includes the input-output stream library which is necessary for using `cout`.
   - `using namespace std;`: This line allows direct access to the standard library objects and functions without prefixing them with `std::`.

2. **Node Structure:**
   - A node in the linked list is defined using a struct called `node`.
   - It contains:
     - `int data;`: An integer to store data.
     - `NodePtr link;`: A pointer (`NodePtr`) to the next node in the list.

3. **Typedef Declaration:**
   - `typedef struct node* NodePtr;` creates a type alias `NodePtr` for a pointer to a `node` structure.

4. **Print Function:**
   - `void print(NodePtr head)`: This function takes the head of the list as an argument and prints each node’s data.
   - Inside the function, a for-loop iterates through the list until it reaches the end (`NULL`).
   - `cout << ptr->data << " ";` outputs the data of each node followed by a space.
   - After the loop, `cout << endl;` outputs a newline character.

**Problem 1**

- The array contains all 10 different integers. Store them in a linked list in order and print them out.

**Array Visualization:**

```
4
3 4
3 4 6
3 4 6 1
3 4 6 1 10
1 3 4 6 9 10
1 3 4 5 6 9 10
1 3 4 5 6 8 9 10
1 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10
```

**C++ Code:**

```cpp
int main()
{
    int A[10] = { 4, 3, 6, 1, 10, 9, 5, 8, 7, 2 };

    return 0;
}
```

**Explanation of the Task:**
- You are given an array consisting of 10 different integers. The task is to store these integers into a data structure called a linked list, where they should be arranged in order. Finally, you are required to print the ordered sequence of integers.

**Explanation of the Diagram:**
- The diagram on the left visually represents the process of ordering the integers step by step. Each step shows the intermediate ordering of integers as new elements are added:

  - Starts with adding the integer 4.
  - Then adds 3 and places it in the correct position before 4.
  - The process continues, adding each subsequent integer and inserting it into its correct position in the sequence, resulting in a fully ordered sequence by the final step.
