c# - LINQ Group by for keyvaluepair data -


hello using linq in asp.net mvc application questions per ids inserted in answer table.

i have table data this:

enter image description here

here in above picture can see scheduleid there in 2 tables first table used assign question scheduleid's , second table storing answer of questions scheduleid.

now have take questions of scheduled question table , answer of question's answer how many star customer has given. 5 star , 4 star, 3 star etc... etc...

so in second table have given example questionid 1 there 4 answers given scheduleid 7543.

i want take data such way questions list count of given answer questionid 1 have 4 answers

q1 5(2 times) q1 2(1 time) q1 2(3 time)

like have created 1 class:

public class question     {         public int questionid { get; set; }         public string questiontext { get; set; }         public list<keyvaluepair<string,string>> answerlist { get; set; }     }

so per above class

i have written query:

list<question> questionlist = (from queans in context.get<guestratinganswers>()                                            join regque in context.get<guestrankingquestions>()                                             on queans.questionid equals regque.id                                            orderby queans.questionid, queans.addedon descending                                            group new { queans, regque } new                                            {                                                queans.questionid,                                                regque.question,                                                regque.addedon                                            }                                g                                            select new question                                            {                                                questionid = g.key.questionid,                                                questiontext = g.key.question                                                //answerlist = new list<keyvaluepair<string, string>>()                                            }).orderby(n => n.questionid).tolist();              foreach (var item in questionlist)             {                  var detail = (from queans in context.get<guestratinganswers>()                 .groupby(n => n.answer).                      select(grp => new keyvaluepair<string, string>(grp.key.tostring(), grp.count().tostring()))).tolist();                  var details = (from queans in context.get<guestratinganswers>()                                orderby queans.answer descending                                group new { queans } new                                {                                    queans.answer                                }                                 g                                select new keyvaluepair<string, string>(g.key.answer.tostring(), g.key.answer.tostring()));             }

in above query in each want answer count of answer keyvaluepair incomplete complete or there mistake have done please mention.

query used var detail , details both different given test.

thanks in advance. :)

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...
