Submitted by Nidhi, on June 27, 2021

Problem Solution:

Here, we will create two sets of integer elements using the Set collection. Then we will perform a subtraction operation between created sets using subtracting() function.

Program/Source Code:

The source code to perform subtraction operation between two Set collections is given below. The given program is compiled and executed successfully.

// Swift program to perform subtraction operation 
// between two Set collections

import Swift

var FirstSet:Set<Int>  = [2,3,5]
var SecondSet:Set<Int> = [1,2,6] 

print("First set : ",FirstSet)
print("Second set: ",SecondSet)
print("Subtraction of set(FirstSet-SecondSet): ",FirstSet.subtracting(SecondSet))

Output:

First set :  [3, 5, 2]
Second set:  [1, 2, 6]
Subtraction of set(FirstSet-SecondSet):  [5, 3]

...Program finished with exit code 0
Press ENTER to exit console.

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 subtracting() function to perform the subtraction operation and printed the result on the console screen.
