C# | Check if a SortedSet object is a proper 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>.IsProperSubsetOf(IEnumerable<T>) method is used to check if a SortedSet<T> object is a proper 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.IsProperSubsetOf(mySet2);
Here, mySet1 and mySet2 are the objects of two SortedSets.
Return Value: This method return True if the SortedSet<T> object is a proper subset of other, otherwise False.
Below programs illustrate the use of SortedSet<T>.IsProperSubsetOf(IEnumerable<T>) method:
Example 1:
// C# code to Check if a SortedSet is a // proper 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 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 subset // of the specified collection // It should return true as SortedSet mySet2 // is a proper subset of SortedSet mySet1 Console.WriteLine(mySet2.IsProperSubsetOf(mySet1)); } } |
Output:
True
Example 2:
// C# code to Check if a SortedSet is a // proper 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( "E" ); // 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( "E" ); // Check if a SortedSet is a proper subset // of the specified collection // It should return true as SortedSet mySet1 // is proper subset of SortedSet mySet2 Console.WriteLine(mySet2.IsProperSubsetOf(mySet1)); } } |
Output:
True
