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
To return a collection with repeated elements in C#, use Enumerable.Repeat method.It is part of System.Linq namespace.Let’s say you need to repeat a number twice, for that set the number and the frequency of repetition.Enumerable.Repeat(50, 2);Now assign it to a variable and display it.Example Live Demousing System; using System.Linq; class Demo { static void Main() { // repeating element 50, two times var num = Enumerable.Repeat(50, 2); // displayig repeating elements foreach (int ele in num) { Console.WriteLine(ele); } } }Output50 50
Use the Convert.ToInt32() method to convert a specified value to a 32-bit signed integer.Let us take a double variable.double doubleNum = 11.53;Now, we will convert it to Int32 using the Convert.ToInt32 method.int intNum; ntNum = Convert.ToInt32(doubleNum);Example Live Demousing System; public class Demo { public static void Main() { double doubleNum = 11.53; int intNum; intNum = Convert.ToInt32(doubleNum); Console.WriteLine("Converted {0} to {1}", doubleNum, intNum); } }OutputConverted 11.53 to 12
In a Linked List, if you want to add a node at the first position, use AddFirst method.Let’s first set a LinkedList.string [] students = {"Jenifer", "Angelina", "Vera"}; LinkedList list = new LinkedList(students);Now, to add an element as a first node, use AddFirst() method.List.AddFirst(“Natalie”);Example Live Demousing System; using System.Collections.Generic; class Demo { static void Main() { string [] students = {"Jenifer", "Angelina", "Vera"}; LinkedList list = new LinkedList(students); foreach (var stu in list) { Console.WriteLine(stu); } // add a node ...
