# C#: Test whether a given non-negative number is a multiple of 13 or it is one more than a multiple of 13

## C# Sharp Basic Algorithm: Exercise-42 with Solution

Write a C# Sharp program to test if a given non-negative number is a multiple of 13 or one more than a multiple of 13.

**Sample Solution**:-

**C# Sharp Code:**

```
using System;
using System.Linq;
namespace exercises
{
// Class declaration
class Program
{
// Main method - entry point of the program
static void Main(string[] args)
{
// Calling the 'test' method with different integers and printing the results
Console.WriteLine(test(13)); // Output: True
Console.WriteLine(test(14)); // Output: True
Console.WriteLine(test(27)); // Output: False
Console.WriteLine(test(41)); // Output: True
Console.ReadLine(); // Keeping the console window open
}
// Method to check if a number is either a multiple of 13 or has a remainder of 1 when divided by 13
public static bool test(int n)
{
// Check if the remainder when 'n' is divided by 13 is either 0 or 1
return n % 13 == 0 || n % 13 == 1;
}
}
}
```

Sample Output:

True True True False
