returning the largest and smallest numbers as an array

Question

I'm trying to return the largest and the smallest numbers in an array as an array

for example: int[] arr = {5, 1, 2, 4, 9, 10, 200}

public static int[] largest_smallest(int[] arr)
{
    
    
    int max = array_values.Max();
    int min = array_values.Min();
    
   //return array with largest and smallest numbers
}

How do I modify my code so it can have an output of: [200, 1]?

Do you know how to declare an array?? Declare an array and add these values to it and return that array — Hogan, Jul 06 '22 at 17:26

Is it possible to add an element to an array after it's initialized in c#? — MjSudo, Jul 06 '22 at 17:28
That works @ralf -- trying to be clear to someone new to programming. — Hogan, Jul 06 '22 at 17:31

Here is a code example that returns an array with the smallest and the largest number:

int[] arr = { 3, 1, 2, 4, 9, 10, 200 };

int[] largestAndSmallest(int[] arr)
{
    int[] result = new int[2];
    result[0] = arr[0];
    result[1] = arr[0];
    for (int i = 1; i < arr.Length; i++)
    {
        if (arr[i] > result[1])
        {
            result[1] = arr[i];
        }
        if (arr[i] < result[0])
        {
            result[0] = arr[i];
        }
    }
    return result;
}

Console.WriteLine(string.Join(", ", largestAndSmallest(arr)));

Using System.Linq;

int[] op_array = {};

op_array[0] = array_values.Max();

op_array[1] = array_values.Min();

You can't set elements with index 0 or 1 on an array with length 0. – NineBerry Jul 06 '22 at 17:37
