ASP.NET Core ApiVersioning change middleware hierarchy -


i have problem middleware hierarchy. created simple web api 1 controller/action

[route("api/v1/values")]   public class valuescontroller : controller   {     // api/v1/values/5     [httpget("{id}")]     public async task<iactionresult> get(string id)     {       return await task.run<iactionresult>(() =>       {         if (id == "nf")         {           return notfound();         }          return ok($"value: {id}");       });     }   }

i configured routing use mvc if match or write default response if not. 

app.usemvc();  app.use(async (context, next) => {   await context.response.writeasync("default"); });

and works great, below can see sample requests/responses: 

/api/v1/values/1 -> 200, body: "value: 1" /api/v1/values/nf -> 404 /api/v1/values -> "default"

great, added apiversioning, controller looks this: 

[apiversion("1")] [route("api/v{version:apiversion}/values")] public class valuescontroller : controller

and added startup : services.addapiversioning();. break routing completely, each request response "default", when remove last app.use, routing works fine values controller, don't have default middleware. know how can responses same prevously, apiversioning?

try this.

[apiversion("1.0")] [route("api/v{version:apiversion}/foo")] public class foocontroller {}

and in startup class

 public void configureservices(iservicecollection services)         {             services.addapiversioning(options =>             {                 options.reportapiversions = true;                 options.assumedefaultversionwhenunspecified = true;                 options.defaultapiversion = new apiversion(1, 0);             });         }

i have tried , worked me.

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...
