Swift program to check a set is the strict superset of another set collection

Program/Source Code:

The source code to check a set is the strict superset of another set collection is given below. The given program is compiled and executed successfully.

// Swift program to check a set is the strict superset 
// of another set collection

import Swift

var FirstSet:Set<Int>  = [1,2,3,4]
var SecondSet:Set<Int> = [2,3]

print("First set : ",FirstSet)
print("Second set: ",SecondSet)

if(FirstSet.isStrictSuperset(of: SecondSet))
{
    print("FirstSet is the strict superset of SecondSet.")
}
else
{
    print("FirstSet is not strict superset of SecondSet.")
}

Output:

First set :  [1, 4, 2, 3]
Second set:  [3, 2]
FirstSet is the strict superset of SecondSet.

Explanation:

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift

Here, we created two sets FirstSet, SecondSet that contains integer elements. Then we used isStrictSuperset() function to check FirstSet is the strict superset of SecondSet using isSuperset() function. The isStrictSuperset() function return Boolean value and then we printed the appropriate message on the console screen.
