C# | Check if a SortedSet object is a proper superset of the specified collection - Coding

SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet<T>.IsProperSupersetOf(IEnumerable<T>) method is used to check whether a SortedSet object is a proper superset 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.IsProperSupersetOf(mySet2);

Here, mySet1 and mySet2 are the objects of two SortedSet.

Return Value: This method returns True if the SortedSet<T> object is a proper superset of other, otherwise returns False.

Exception: This method will give ArgumentNullException if the SortedSet is null.

Below programs illustrate the use of SortedSet<T>.IsProperSupersetOf(IEnumerable<T>) method:

Example 1:

// C# code to Check if a SortedSet is a 
// proper superset 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 
        for (int i = 0; i < 10; i++) { 
            mySet1.Add(i); 
        } 
  
        // 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 proper superset 
        // of the specified collection 
        // It should return false as SortedSet mySet2 
        // is not a proper superset of SortedSet mySet1 
        Console.WriteLine(mySet2.IsProperSupersetOf(mySet1)); 
    } 
} 

Output:

False

Example 2:

// C# code to Check if a SortedSet is a 
// proper superset 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 proper superset 
        // of the specified collection 
        // It should return true as SortedSet mySet1 
        // is proper superset of SortedSet mySet2 
        Console.WriteLine(mySet1.IsProperSupersetOf(mySet2)); 
    } 
} 

Output:

True
