Yesterday, I was sitting with my college friends at a coffee shop. One of my friends asked me a question that how we can find highest second and lowest second number in a particular array, and without the help of any function like orderBy. So, I took a notebook and solved his question. Now I am writing a blog on that logic as I want to share my logic with everybody.

Here is my code:-

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

public partial class secondHighestLowest : System.Web.UI.Page

{

// this is an array.

int[] arr = new int[10] { 45, 3, 64, 6, 24, 75, 3, 6, 24, 45 };

protected void Page_Load(object sender, EventArgs e)

{

// calling second highest number method.

secondHighestNumber();

// calling second lowest number method.

secoundLowestNumber();

}

/// <summary>

/// In this function I will get second highest number.

/// </summary>

private void secondHighestNumber()

{

int firstHighestNumber = arr[0];

int secondHighestNumber = arr[0];

// first I am getting highest number of array.

for(int i = 0; i<arr.Length; i++)

{

if (arr[i]>firstHighestNumber)

{

firstHighestNumber = arr[i];

}

}

// when I got highest number of array, then I will check the second highest number of array.

// in if condition I am getting second highest number of array which is not equal to first

// highest number.

for (int x = 0; x < arr.Length; x++)

{

if (arr[x]>secondHighestNumber && firstHighestNumber!=arr[x])

{

secondHighestNumber = arr[x];

}

}

// showing second highest number.

Response.Write("secondHighestNumber---- " + secondHighestNumber + "</br>");

}

/// <summary>

/// In this function I will get second lowest number.

/// </summary>

private void secoundLowestNumber()

{

int firstLowestNumber = arr[0];

int secondLowestNumber = arr[0];

// first I am getting lowest number of array.

for (int i = 0; i < arr.Length; i++)

{

if (arr[i] < firstLowestNumber)

{

firstLowestNumber = arr[i];

}

}

// when I got lowest number of array, then I will check the lowest highest number of array.

// in if condition I am getting second lowest number of array which is not equal to first

// lowest number.

for (int x = 0; x < arr.Length; x++)

{

if (arr[x] < secondLowestNumber && firstLowestNumber != arr[x])

{

secondLowestNumber = arr[x];

}

}

// showing second lowest number.

Response.Write("secondLowestNumber---- " + secondLowestNumber + "</br>");

}

}

Cheers!!

Happy coding:)
