Question
using System;
class Program
{
publicstaticvoid Main(string[] args)
{
int number = 1;
while (number <= 50)
{
Console.WriteLine(number);
number = number + 1;
{
number = 100;
while (number <= 109)
{
Console.WriteLine(number);
number = number + 1;
}
}
}
}
}

hello, how can this program be fixed to count from 1-50 and then count from 70-200?
## Understanding Nested Loops in C#

The following lesson focuses on understanding and implementing nested loops in C#. Below is a sample C# program accompanied by its output:

### Program Code

```csharp
using System;
class Program
{
    public static void Main(string[] args)
    {
        int number = 1;
        while (number <= 50)
        {
            Console.WriteLine(number);
            number = number + 1;
            {
                number = 100;
                while (number <= 109)
                {
                    Console.WriteLine(number);
                    number = number + 1;
                }
            }
        }
    }
}
```

### Explanation
Let's break down the key components and logic of this program:

1. **Namespace and Class Declaration:**
   ```csharp
   using System;
   class Program
   ```
   - This sets up the basic structure and imports the required namespace for console operations.

2. **Main Method:**
   ```csharp
   public static void Main(string[] args)
   ```
   - The `Main` method is the entry point of the program.

3. **Variable Initialization:**
   ```csharp
   int number = 1;
   ```
   - An integer variable `number` is initialized to 1.

4. **Outer While Loop:**
   ```csharp
   while (number <= 50)
   ```
   - This loop runs while `number` is less than or equal to 50.
   - Within this loop, `number` is incremented by 1 and printed to the console.

5. **Inner Block:**
   ```csharp
   {
       number = 100;
       while (number <= 109)
       {
           Console.WriteLine(number);
           number = number + 1;
       }
   }
   ```
   - After printing the numbers up to 50, `number` is set to 100.
   - The inner `while` loop runs while `number` is less than or equal to 109. This prints the numbers from 100 to 109.

### Output

When the program is executed, the following output is generated:

```
1
100
101
102
103
104
105
106
107
108
109
```

### Explanation of Output

1. The program starts with `number` at 1 and prints it.
2. Before it can increment and print numbers up to
