here is the question

Create a program named Reverse3whose Main() method declares three integers named firstInt, middleInt, and lastInt.

Assign the following values to the integers:

• 23 to firstInt
• 45 to middleInt
• 67 to lastInt

Then display the values and pass them to a method named Reversethat accepts them as reference variables, places the first value in the lastInt variable, and places the last value in the firstIntvariable.

In the Main() method, display the three variables again, demonstrating that their positions have been reversed.

here is my code it says its wrong

using System;

class Reverse3 {

static void Reverse (ref int first, ref int mid, ref int last)

{

int firstInt = 1, middleInt = 2, lastInt = 3;

Reverse3.Reverse(ref firstInt, ref middleInt, ref lastInt);

Assert.AreEqual(firstInt, 3);

Assert.AreEqual(middleInt, 2);

Assert.AreEqual(lastInt, 1);

}

}

static void Main() {

//declares three integers named

int firstInt = 23;

int middleInt = 45;

int lastInt = 67;

//Then display the values

Console.WriteLine("FirstIntInt = "+ firstInt +

", MiddleInt = "+ middleInt +

", LastInt = "+ lastInt);

Reverse(ref firstInt,ref middleInt, ref lastInt);

Console.WriteLine("FirstIntInt = "+ firstInt +

", MiddleInt = "+ middleInt +

", LastInt = "+ lastInt);

}

}
