<script>         var ar = [];         var yr=[]         var br = [];         var yr = [];         var prdname = [];         var prdqty = [];         var c = [];           var data = [];         var productname = ['year'];           var polishmaster = json.parse('@html.raw(json.encode(viewdata["productssoldperyear"]))');          $.each(polishmaster, function (index, item) {             var array = {};              array.year = item.year;             //yr = item.year;             array.productquantity = item.productquantity;             //prdqty = item.productquantity;             array.productname = item.productname;             //prdname = item.productname;             ar.push(array);           });         var main = [];         var min = 0, max = 0;         (var = 0; < ar.length; i++)         {             var b = ar[i];             var = [b.year, b.productquantity];               productname.push(b.productname);              for(var j=i+1;j<ar.length;j++)             {                 var c = ar[j];                 if(b.year==c.year)                 {                     productname.push(c.productname);                     a.push(c.productquantity);                      ar = jquery.grep(ar, function (value) {                         return value != c;                     });                  }              }              max = a.length + 1;             min =0 ;              if ( max<a.length+1)             {                 max = a.length + 1;             }                data.push(a);         }         alert(max)             (var l = 0; l < data.length; l++) {            debugger;                 var ab = data[l];                 if (ab.length != productname.length)                 {                     var ll = ab.length;                     (var kk = ll; kk <productname.length; kk++)                     {                        ab.push(0);                     }                     main.push(ab);                     console.log(ab);                 }                }              var header = productname;         var jsondata = [header].concat(data);         function drawchart() {                      var data = google.visualization.arraytodatatable(                 jsondata            );             // define chart drawn.             //var data = google.visualization.arraytodatatable([             //   ['year', 'asia', 'europe'],             //   ['2012', 900, 390],             //   ['2013', 1000, 400],             //   ['2014', 1170, 440],             //   ['2015', 1250, 480],             //   ['2016', 1530, 540]             //]);              var options = {                 title: 'product sold per year',                 isstacked: true             };              // instantiate , draw chart.             var chart = new google.visualization.barchart(document.getelementbyid('container'));             chart.draw(data, options);         }         google.charts.setonloadcallback(drawchart);     </script>

here in polishmaster getting data code follows

 public list<datewisestockdetailviewmodel> getproductsoldbyyear(int companyid)         {             var userdata = (from m in datewise.getall()                             join s in stock.getall()                             on m.stock_id equals s.stock_id                             join p in product.getall()                             on s.productid equals p.productid                             s.companyid == companyid && m.isproductdeducted == true                             group new { m,s, p } new { convert.todatetime(m.createddate.tostring()).year,p.productname ,p.productid } g                             select new datewisestockdetailviewmodel                             {                                 productid = convert.toint32(g.key.productid),                                 productname=g.key.productname,                                 productquantity = g.sum(x => x.m.productquantity),                                 year = g.key.year.tostring()                             }).distinct().tolist<datewisestockdetailviewmodel>();             return userdata;         }

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...
