C# | Check if a SortedSet is a subset of the specified collection
SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet<T>.IsSubsetOf(IEnumerable<T>) Method is used to check whether a SortedSet<T> object is a subset of the specified collection or not.
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 :
mySet1.IsSubsetOf(mySet2);
Here, mySet1 and mySet2 are SortedSets.
Return Value: This method returns True if the SortedSet<T> object is subset of other, otherwise false.
Exception: This method returns the ArgumentNullException if the SortedSet is null.
Example 1:
// C# code to Check if a SortedSet is a // subset of the specified collection using System; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Creating a SortedSet of integers SortedSet< int > mySet1 = new SortedSet< int >(); // Inserting elements in SortedSet mySet1.Add(2); mySet1.Add(3); mySet1.Add(4); mySet1.Add(5); // Creating a SortedSet of integers SortedSet< int > mySet2 = new SortedSet< int >(); // Inserting elements in SortedSet mySet2.Add(3); mySet2.Add(4); mySet2.Add(5); mySet2.Add(6); // Check if a SortedSet is a subset // of the specified collection // It should return false as SortedSet mySet2 // is not a subset of SortedSet mySet1 Console.WriteLine(mySet2.IsSubsetOf(mySet1)); } } |
Output:
False
Example 2:
// C# code to Check if a SortedSet is a // subset of the specified collection using System; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Creating a SortedSet of strings SortedSet< string > mySet1 = new SortedSet< string >(); // Inserting elements in SortedSet mySet1.Add( "A" ); mySet1.Add( "B" ); mySet1.Add( "C" ); mySet1.Add( "D" ); mySet1.Add( "A" ); // Creating a SortedSet of strings SortedSet< string > mySet2 = new SortedSet< string >(); // Inserting elements in SortedSet mySet2.Add( "B" ); mySet2.Add( "C" ); mySet2.Add( "D" ); mySet2.Add( "D" ); // Check if a SortedSet is a subset // of the specified collection // It should return true as SortedSet mySet2 // is subset of SortedSet mySet1 Console.WriteLine(mySet2.IsSubsetOf(mySet1)); } } |
Output:
True
