## How can we find highest second and lowest second number in a particular array?

/5

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:)
