C# Program to create a LinkedList
A LinkedList in C# is a generic collection that stores elements in nodes, where each node contains the data and references to the next and previous nodes. Unlike arrays, LinkedList elements are not stored in contiguous memory locations and allow efficient insertion and removal operations. Syntax Following is the syntax for creating a LinkedList − LinkedList listName = new LinkedList(); You can also create a LinkedList from an existing collection − LinkedList listName = new LinkedList(collection); Creating LinkedList from Array You can create a LinkedList by passing an array ...
Read MoreHow to find the Sum of two Binary Numbers using C#?
Adding two binary numbers in C# involves performing binary arithmetic bit by bit, just like manual addition but working in base-2. The process includes handling carry operations when the sum of bits exceeds 1. Binary addition follows simple rules: 0 + 0 = 0, 0 + 1 = 1, 1 + 0 = 1, and 1 + 1 = 10 (which means 0 with a carry of 1). Syntax Following is the basic approach for binary addition − // Extract rightmost bits bit1 = val1 % 10; bit2 = val2 % 10; // Calculate ...
Read MoreC# program to find the index of a word in a string
Finding the index of a word in a string or array is a common programming task in C#. The Array.IndexOf() method provides an efficient way to locate the position of a specific element within an array of strings. Syntax Following is the syntax for using Array.IndexOf() method − int index = Array.IndexOf(array, searchValue); Parameters array − The one-dimensional array to search searchValue − The object to locate in the array Return Value The method returns the index of the first occurrence of the specified value. If the value is ...
Read MoreC# Program to invert the order of elements in a sequence
In C#, you can invert the order of elements in a sequence using several built-in methods. The most common approaches include using Queryable.Reverse() with LINQ, Array.Reverse(), and Enumerable.Reverse(). Each method has its specific use cases and performance characteristics. Syntax Following is the syntax for using Queryable.Reverse() method − IQueryable result = sequence.AsQueryable().Reverse(); Following is the syntax for using Array.Reverse() method − Array.Reverse(array); Following is the syntax for using Enumerable.Reverse() method − IEnumerable result = sequence.Reverse(); Using Queryable.Reverse() Method The Queryable.Reverse() method returns an IQueryable that ...
Read MoreDecimal.ToString() Method in C#
The Decimal.ToString() method in C# is used to convert the numeric value of a decimal instance to its equivalent string representation. This method provides various overloads to format the decimal value according to specific requirements. Syntax Following is the basic syntax for Decimal.ToString() method − public override string ToString(); The method also has overloaded versions for custom formatting − public string ToString(string format); public string ToString(IFormatProvider provider); public string ToString(string format, IFormatProvider provider); Parameters format − A standard or custom numeric format string (optional). provider − An object ...
Read MoreWhat does Array.IsSynchronized property of array class do in C#?
The Array.IsSynchronized property in C# gets a boolean value indicating whether access to the Array is synchronized (thread-safe). This property is part of the ICollection interface implementation and helps determine if an array can be safely accessed by multiple threads simultaneously. For standard C# arrays, this property always returns false, meaning that arrays are not inherently thread-safe. When multiple threads need to access the same array, you must implement your own synchronization using the SyncRoot property or other synchronization mechanisms. Syntax Following is the syntax for the Array.IsSynchronized property − public bool IsSynchronized { get; ...
Read MoreHow are values assigned to arrays in C#?
Declaring an array does not initialize the array in memory. When the array variable is initialized, you can assign values to the array using several different approaches in C#. Array is a reference type, so you need to use the new keyword to create an instance of the array. There are multiple ways to assign values to arrays, each with its own syntax and use cases. Syntax Following is the syntax for declaring and initializing arrays − // Declaration with size datatype[] arrayName = new datatype[size]; // Assignment using index arrayName[index] = value; ...
Read MoreHow to get the nth value of a Fibonacci series using recursion in C#?
The Fibonacci series is a sequence where each number is the sum of the two preceding numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21... In C#, we can use recursion to calculate the nth Fibonacci number by breaking the problem into smaller subproblems. Recursion works by having the method call itself with reduced parameters until it reaches a base case. For Fibonacci, the base cases are F(0) = 0 and F(1) = 1. Syntax Following is the syntax for a recursive Fibonacci method − public int Fibonacci(int n) { if ...
Read MoreC# Program to return a collection with repeated elements
To return a collection with repeated elements in C#, use the Enumerable.Repeat method from the System.Linq namespace. This method creates a sequence that contains one repeated value a specified number of times. Syntax Following is the syntax for Enumerable.Repeat method − public static IEnumerable Repeat(TResult element, int count) Parameters element − The value to be repeated in the result sequence. count − The number of times to repeat the value in the generated sequence. Return Value Returns an IEnumerable that contains a repeated value. ...
Read MoreHow to use Remove, RemoveAt, RemoveRange methods in C# list collections?
C# provides several methods to remove elements from List collections. The Remove() method removes the first occurrence of a specific value, RemoveAt() removes an element at a specific index, and RemoveRange() removes multiple consecutive elements. Syntax Following is the syntax for the three removal methods − // Remove by value (first occurrence) bool Remove(T item) // Remove by index void RemoveAt(int index) // Remove range of elements void RemoveRange(int index, int count) Parameters Remove(T item): The item to remove from the list. Returns true if item is found and removed. ...
