以特定模式交换数组

问题描述：

我的数组如下：

My array is like:

11  22  33  44  55  66  77  88  99  110

和交换就像这样完成

and the swapping is to be done like this

22  11  44  33  66  55  88  77  110  90

ASP.NET C＃控制台应用程序，

所以有人可以帮我这个

ASP.NET C# console application,
so can anyone please help me for this

class Program
    {
        static void Main()
        {
            int i,n;

            //Enter Number of elements in an array
            Console.WriteLine("Enter no array elements : ");
            n = Convert.ToInt32(Console.ReadLine());



            // Enter elements to an array
            int[] arr = new int[n];           
            Console.WriteLine("Enter the array elements : ");
            for(i=0; i<arr.length;>            {
                arr[i] = Convert.ToInt32(Console.ReadLine());
            }


            //Display Array Elements
            Console.WriteLine("Array Elements are :");
            for (i = 0; i < arr.Length; i++)
            {
                Console.WriteLine(arr[i] + "\t");
            }


            //Logic Starts From Here
            if (arr.Length == 1)
            {
                Console.WriteLine("Too Les Items to be shorted");
            }
            else
            {
                int start, end, mid;
                start = arr[0];
                end = arr[n-1];
                Console.WriteLine("Start and End are " + start + "\t  and \t" + end);

                for (i = 0; i < n - 1; i++)
                {
                    arr[n - 1] = arr[i];
                }

                Console.WriteLine(" NEWArray Elements are :");
                for (i = 0; i < arr.Length; i++)
                {
                    Console.WriteLine(arr[i] + "\t");
                }
                ;
            }

            Console.ReadKey();

答

试试这个

Try this

// swap
int tmp;
for (i = 0; i < arr.Length- 1; i+=2)
{
    tmp= arr[i + 1];
    arr[i + 1] = arr[i];
    arr[i]= tmp;
}

int [] arr = new int [10];

int i;

Console.WriteLine（输入数组元素：）;

for（i = 0; i< arr.length;> {

Console.WriteLine （arr [i] +\t）;

}

====================

然后

start = a [0];

end = a [n-1];

for（i = 0; i< n-1;> {

a [n-1] = a [i];

}

这是正确的方式..？

int[] arr = new int[10];
int i;
Console.WriteLine("Enter the array elements : ");
for(i=0; i<arr.length;> {
Console.WriteLine(arr[i] + "\t");
}
====================

then after
start = a[0];
end = a[n-1];

for(i=0; i<n-1;>{
a[n-1] = a[i];
}

is it the right way..?

试试这个

try this

using System;
using System.Collections.Generic;
using System.Data.SqlClient;
using System.Linq;


class Program
{
    static void Main(string[] args)
    {
        int[] input = { 11, 22, 33, 44, 55, 66, 77, 88, 99, 110 };
        int[] output = new int[10];
        int count = 0;
        for (int i = 0; i < input.Length; i++)
        {
            count++;
            if (count == 2)
            {
                output[i - 1] = input[i];
                output[i] = input[i - 1];
                count = 0;
            }
        }

        Console.WriteLine(" Output  :");
        for (int i = 0; i < output.Length; i++)
            Console.WriteLine(output[i] + "\t");

        Console.ReadKey();
    }
}
