Introduction Solution I think a cleaner answer uses the built-in enumerate and zip functions: Dlist = [17,13,10,6,2] Ilist = [5,9,10,15,18] def seqsearch(DS,IS): for idx, (d, s) in enumerate(zip(DS, IS)): if d == s: return f”Yes! Found at index = {idx}” return “No!\n-1” print(seqsearch(Dlist,Ilist)) It’s unclear whether you want to return just the first index, or … Read more
Introduction Solution The reason you’re getting the compiler error is that you’ve pushed the generic constrains to the individual methods rather than putting the restraint on the class. The way you have it, there’s no way to override the intrinsically generic method GetOrderingFunc<T> with a method that returns a Expression<Func<User, string>>. What you’ve posted works … Read more
Introduction Solution If you add use strict and use warnings you’ll probably get some feedback about needing to declare @tran in the code below: while(my @row = $tran->fetchrow_hash) { my $tran = join ‘,’, @row; $trans{$tran[2]}{$tran[3]} += $tran[4]; } $tran is 657520,02-07-1999,016901581432,Debit,16000 when you try and use it as an array. Use Data::Dumper to show … Read more
Introduction Solution You can do it easily with XDocument var xDocument = XDocument.Parse(@”<configuration> <property> <name>name</name> <value>dinesh</value> </property> <property> <name>city</name> <value>Delhi</value> </property> </configuration>”); var firstPropertyElement = xDocument .Descendants(“property”) .First();//Find your element var xComment = new XComment(firstPropertyElement.ToString());//Create comment firstPropertyElement.ReplaceWith(xComment);//Replace the element with comment Console.WriteLine(xDocument); Which outputs: <configuration> <!–<property> <name>name</name> <value>dinesh</value> </property>–> <property> <name>city</name> <value>Delhi</value> </property> </configuration>
