C# Program to Swap the Max and Min Array Element

C# Program to Swap the Max and Min Array Element

Most of the IT companies check the coding skills and problem-solving skills as well along with the theoretical interview questions. Sometimes you are free to write the pseudo code and sometimes you are asked to write the complete program either on any paper or any editor. 

This question is asked in the coding interview to write the program. Here you can find the program as well as a live running program so that you can test the program immediately.

using System;

public class Program
{
public static void Main()
{
	int[] unsortedArray = new int[8] {1, 5,  6, 8, 3, 7, 2, 4};			
			
	Console.WriteLine("Input UnSorted Array: ");	
	Console.WriteLine("------------------------------------------------ ");	
	for( int i = 0; i < unsortedArray.Length; i++)
	{
		Console.WriteLine(unsortedArray[i]);
	}		
	
	var arrayAfterSwapping = MinMaxArraySwap(unsortedArray);
	
	Console.WriteLine("\n\nArray After Min Max Element Swapping: ");	
	Console.WriteLine("------------------------------------------------ ");	
	for( int i = 0; i < arrayAfterSwapping.Length; i++)
	{
		Console.WriteLine(arrayAfterSwapping[i]);
	}						
}	
	
public static int[] MinMaxArraySwap(int[] array)
{
	int min = 0;
	int max = 0;

	for (int i = 1; i < array.Length; i++)
	{
		if (array[min] > array[i])
			min = i;
		if (array[max] < array[i])
			max = i;
	}
	int temp = array[min];
	array[min] = array[max];
	array[max] = temp;
	
	return array;
}
}

Output: 

                Input UnSorted Array: ------------------------------------------------ 1 5 6 8 3 7 2 4 Array After Min Max Element Swapping: ------------------------------------------------ 8 5 6 1 3 7 2 4
