Using C# Write a program that performs the following. The user inputs a number and then enters a series of numbers from 1 to that number. Your program should determine which number (or numbers) is missing or duplicated in the series, if any. For example, if the user entered 5 as the initial number and then entered the following sequences, the results should be as shown. Input Sequence Output ---------------------- --------------- 1 2 3 4 5 Nothing bad However, if 7 were the high number, the user would see the results on the right for the following number entries: Input Sequence Output ---------------------- --------------- 1 3 2 4 5 Missing 6 Missing 7 And if 10 were the high number and the user entered the numbers shown on the left, note the list of missing and duplicate numbers: Input Sequence Output ---------------------- --------------- 1 2 4 7 4 4 5 10 8 2 6 Duplicate 2 ( 2 times) Missing 3 Duplicate 4 ( 3 times ) Missing 9 The program should check the high number that the user inputs to ensure that it does not exceed the size of any array you might be using for storage.

Hello I am hosting remoting within IIS. Everything works just fine as long as I allow anonymous access at the IIS level. When I allow only Windows Authenticated sessions, something very strange happens: If the client activates the remote object with IP address - works fine If the client activates it using a machine name - get http 401 exception is thrown. The exception is thrown when the client calls the remote method. I set the channel's useDefaultCredentials property to true. Any idea how to allow Windows Authentication? Here is the call stack: System.Net.WebException: The remote server returned an error: (401) Unauthorized .. ---> System.ComponentModel.Win32Exception: The target principal name is incorrect at System.Net.NTAuthentication.GetOutgoingBlob(Byte[] incomingBlob, Boolean handshakeComplete) at System.Net.NTAuthentication.GetOutgoingBlob(String incomingBlob, Boolean handshakeComplete) at System.Net.NegotiateClient.DoAuthenticate(String challenge, WebRequest webRequest, ICredentials credentials, Boolean preAuthenticate) at System.Net.NegotiateClient.DoAuthenticate(String challenge, WebRequest webRequest, ICredentials credentials, Boolean preAuthenticate) at System.Net.NegotiateClient.Authenticate(String challenge, WebRequest webRequest, ICredentials credentials) at System.Net.AuthenticationManager.Authenticate(String challenge, WebRequest request, ICredentials credentials) at System.Net.AuthenticationState.AttemptAuthenticate (HttpWebRequest httpWebRequest, ICredentials authInfo) --- End of inner exception stack trace ---
