xml - c# serialize object without root element -


i working 3rd party has xml structure multiple different requests.

each request has common header structure , specific footer data.

unfortunately, header , footer sections not wrapped within own element tags , can't change.

some sample contrived requests shown below:

sample request 1

<?xml version="1.0" encoding="utf - 8" standalone="yes"?> <request>     <requesttype>1</requesttype>     <user>user01</user>     <id>1234</id>     <name>john</name>     <age>20</age> </request>

sample request 2

<?xml version="1.0" encoding="utf - 8" standalone="yes"?> <request>     <requesttype>2</requesttype>     <user>user02</user>     <id>1235</id>     <school>the school</school>     <teacher>mrs smith</teacher> </request>

sample request 3

<?xml version="1.0" encoding="utf - 8" standalone="yes"?> <request>     <requesttype>3</requesttype>     <user>user01</user>     <id>223</id>     <work>the office</word>     <boss>mr white</boss>     <phone>1234567</phone>     <payday>friday</payday> </request>

you can see each request has requesttype, user , id.

my question relates writing c# code encapsulate xml serialization.

to me, seems wrong have each of c# classes having repeated header (requesttype, user , id) data.

i have tried using generics (see sample code below) leads question.

question: how can serialize generic object footer not wrapped within "root" footer element?

[system.xml.serialization.xmlroot("request")] public class genericrequest<typet> {     public genericrequest()     {     }      public int requesttype { get; set; }      public string user { get; set; }      public int id { get; set; }      public typet footer { get; set; } }

you can create class interface ifooter, can have different implementor per requirement (e.g. 

interface ifooter : iserializable  {  //define common member. }  public class footer1: ifooter {  // define members (e.g. work)  }  public class footer2: ifooter {  // define members  }  public class footer3: ifooter {  // define members  }

now serialize main class 

[system.xml.serialization.xmlroot("request")] public class genericrequest {   public genericrequest()   {   }     public int requesttype { get; set; }    public string user { get; set; }    public int id { get; set; }    public ifooter footer { get; set; } }

visit how can serialize object has interface property? reference.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
