Set a LinkedList.int [] num = {1, 2, 3, 4, 5}; LinkedList list = new LinkedList(num);Now add a node at the end using AddLast() method.var newNode = list.AddLast(20);To add a node after the above added node, use the AddAfter() method.list.AddAfter(newNode, 30);Example Live Demousing System; using System.Collections.Generic; class Demo { static void Main() { int [] num = {1, 2, 3, 4, 5}; LinkedList list = new LinkedList(num); foreach (var n in list) { Console.WriteLine(n); } // adding a node at the ...

The following is our array −int[] points = { 210, 250, 300, 350, 420};Use skip() method to skip elements. Add the number as an argument that displays the number of elements to be returned.IEnumerable skipEle = points.AsQueryable().OrderByDescending(s => s).Skip(3);Example Live Demousing System; using System.Linq; using System.Collections.Generic; public class Demo { public static void Main() { int[] points = { 210, 250, 300, 350, 420}; Console.WriteLine("Initial array..."); foreach (int res in points) Console.WriteLine(res); IEnumerable skipEle = points.AsQueryable().OrderByDescending(s => s).Skip(3); Console.WriteLine("Skipped 3 elements..."); foreach (int res in skipEle) Console.WriteLine(res); } }OutputInitial array... 210 250 300 350 420 Skipped 3 elements... 250 210
Use the Remove() method to remove the first occurrence of a node in a LinkedList.Firstly, let us set a LinkedList with integer elements.int [] num = {2, 5, 7, 15}; LinkedList list = new LinkedList(num);Now, let’s say you need to remove node with element 7. For that, use the Remove() method.list.Remove(7);Let us see the complete code.Example Live Demousing System; using System.Collections.Generic; class Demo { static void Main() { int [] num = {2, 5, 7, 15}; LinkedList list = new LinkedList(num); foreach (var n in list) { ...

Use the Contains() method to check whether a node is a LinkedList or not.Here is our LinkedList.string [] students = {"Beth", "Jennifer", "Amy", "Vera"}; LinkedList list = new LinkedList(students);Now, to check whether the node “Amy” is in the list or not, we will use the Contains() method as shown below −list.Contains("Amy")The method will return a Boolean value i.e. True in this case.Let us see the complete code.Example Live Demousing System; using System.Collections.Generic; class Demo { static void Main() { string [] students = {"Beth", "Jennifer", "Amy", "Vera"}; LinkedList list = new LinkedList(students); ...

To convert a string to lowercase letters in JavaScript, use the toLocaleLowerCase() method.ExampleYou can try to run the following code to learn how to work with toLocaleLowerCase() method in JavaScript −Live Demo var a = "WELCOME!"; document.write(a.toLocaleLowerCase());
Convert a specified value to a 64-bit signed integer using Convert.ToInt64 Method.Let us take a double value.double doubleNum = 193.834;Now, convert it to Int64 i.e. long.long res; res = Convert.ToInt32(doubleNum);Example Live Demousing System; public class Demo { public static void Main() { double doubleNum = 193.834; long res; res = Convert.ToInt32(doubleNum); Console.WriteLine("Converted {0} to {1}", doubleNum, res); } }OutputConverted 193.834 to 194
Convert a specified value to an 8-bit signed integer i.e. SByte.It is a signed 8-bit integer data type which stores value between -128 to 127.Let us see an example. We have a double variable.double doubleNum = -19.9;Now, let us convert it to SByte.sbyte res; res = Convert.ToSByte(doubleNum);Example Live Demousing System; public class Demo { public static void Main() { double doubleNum = -19.9; sbyte res; res = Convert.ToSByte(doubleNum); Console.WriteLine("Converted {0} to {1}", doubleNum, res); } }OutputConverted -19.9 to -20
To find carriage return character with JavaScript Regular Expression, use the following −\rExampleYou can try to run the following code to find a carriage return character. It returns the position where the carriage return (\r) character is found − JavaScript Regular Expression var myStr = "100% \r Responsive!"; var reg = /\r/; var match = myStr.search(reg); document.write(match);
The following is our LinkedList list with nodes.string [] students = {"Katie", "Jennifer", "Amy", "Vera"}; LinkedList list = new LinkedList(students);Now let us remove a node with the string element “Vera”.For that, use Remove() method.list.Remove("Vera");Example Live Demousing System; using System.Collections.Generic; class Demo { static void Main() { string [] students = {"Katie", "Jennifer", "Amy", "Vera"}; LinkedList list = new LinkedList(students); foreach (var stu in list) { Console.WriteLine(stu); } // removing a node list.Remove("Vera"); Console.WriteLine("LinkedList after removing ...

To represent Int32 as a Hexadecimal string in C#, use the ToString() method and set the base as the ToString() method’s second parameter i.e. 16 for Hexadecimal.Int32 represents a 32-bit signed integer.Firstly, set an Int32 variable.int val = 9898;Now, convert it to a hexadecimal string by including 16 as the second parameter.Convert.ToString(val, 16)Example Live Demousing System; class Demo { static void Main() { int val = 9898; Console.WriteLine("Integer: "+val); Console.Write("Hex String: "+Convert.ToString(val, 16)); } }OutputInteger: 9898 Hex String: 26aa
