C# | Check if a SortedSet object is a proper superset 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>.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 collectionusing 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 collectionusing 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
