﻿ C# - Sum 3 integers, if 2 values are same, return the third

# C#: Compute the sum of three given integers. If the two values are same return the third value

## C# Sharp Basic Algorithm: Exercise-55 with Solution

Write a C# Sharp program to compute the sum of three given integers. Return the third value if the two values are the same.

Sample Solution:-

C# Sharp Code:

``````using System; // Import the System namespace which contains fundamental types and base classes
using System.Linq; // Import the LINQ namespace for LINQ functionality

namespace exercises // Define a namespace called 'exercises'
{
class Program // Define a class named 'Program'
{
static void Main(string[] args) // The entry point of the program
{
// Output the result of test function with different sets of three integers as arguments
Console.WriteLine(test(4, 5, 7)); // Test with integers 4, 5, and 7
Console.WriteLine(test(7, 4, 12)); // Test with integers 7, 4, and 12
Console.WriteLine(test(10, 10, 12)); // Test with integers 10, 10, and 12
Console.WriteLine(test(12, 12, 18)); // Test with integers 12, 12, and 18
Console.ReadLine(); // Wait for user input before closing the console window
}

// Function definition of test function that takes three integers 'x', 'y', and 'z' and returns an integer
public static int test(int x, int y, int z)
{
if (x == y && y == z) return 0; // If all three integers are equal, return 0
if (x == y) return z; // If 'x' and 'y' are equal, return 'z'
if (x == z) return y; // If 'x' and 'z' are equal, return 'y'
if (y == z) return x; // If 'y' and 'z' are equal, return 'x'
return x + y + z; // If none of the above conditions match, return the sum of 'x', 'y', and 'z'
}
}
}
```
```

Sample Output:

```16
23
12
18```
