C# | Union of SortedSet to a collection
SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet<T>.UnionWith(IEnumerable<T>) method is used to modify the current SortedSet<T> object so that it contains all elements that are present in either the current object or the specified collection.
Properties:
- In C#, SortedSet class can be used to store, remove or view elements.
- It maintains ascending order and does not store duplicate elements.
- It is suggested to use SortedSet class if you have to store unique elements and maintain ascending order.
Syntax:
mySortedSet1.UnionWith(mySortedSet2);
Here, mySortedSet1 and mySortedSet2 are two SortedSet objects.
Exception: This method will give ArgumentNullException if the SortedSet is null.
Below given are some examples to understand the implementation in a better way:
Example 1:
// C# code to get the Union of 2 SortedSets using System; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Creating a SortedSet of integers SortedSet< int > mySortedSet1 = new SortedSet< int >(); // adding elements in mySortedSet1 mySortedSet1.Add(2); mySortedSet1.Add(4); mySortedSet1.Add(6); mySortedSet1.Add(8); mySortedSet1.Add(10); // Creating a SortedSet of integers SortedSet< int > mySortedSet2 = new SortedSet< int >(); // adding elements in mySortedSet mySortedSet2.Add(4); mySortedSet2.Add(5); mySortedSet2.Add(7); mySortedSet2.Add(8); mySortedSet2.Add(9); Console.WriteLine( "The union of mySortedSet1 and mySortedSet2 is: " ); mySortedSet1.UnionWith(mySortedSet2); // To display the union of mySortedSet1 and mySortedSet2 foreach ( int i in mySortedSet1) { Console.WriteLine(i); } } } |
Output:
The union of mySortedSet1 and mySortedSet2 is: 2 4 5 6 7 8 9 10
Example 2:
// C# code to get the Union of 2 SortedSets using System; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Creating a SortedSet of strings SortedSet< string > mySortedSet1 = new SortedSet< string >(); // adding elements in mySortedSet1 mySortedSet1.Add( "Beginner" ); mySortedSet1.Add( "for" ); mySortedSet1.Add( "Beginner" ); mySortedSet1.Add( "Noida" ); mySortedSet1.Add( "Data Structures" ); // Creating a SortedSet of strings SortedSet< string > mySortedSet2 = new SortedSet< string >(); // adding elements in mySortedSet mySortedSet2.Add( "Beginner" ); mySortedSet2.Add( "Java" ); mySortedSet2.Add( "Beginner Classes" ); mySortedSet2.Add( "C++" ); mySortedSet2.Add( "Noida" ); Console.WriteLine( "The union of mySortedSet1 and mySortedSet2 is: " ); mySortedSet1.UnionWith(mySortedSet2); // To display the union of mySortedSet1 and mySortedSet2 foreach ( string str in mySortedSet1) { Console.WriteLine(str); } } } |
Output:
The union of mySortedSet1 and mySortedSet2 is: C++ Data Structures for Beginner Beginner Classes Java Noida
