Swift Set subtract()

subtract() Syntax

The syntax of the set subtract() method is:

set.subtract(otherSet)

Here, set is an object of the Set class.

subtract() Parameters

The subtract() method takes a single parameter:

• otherSet - The set of elements.

Note: The other must be a finite set.

subtract() Return Value

• The subtract() method returns set after removing the common elements of set and otherSet.

Example 1: Swift Set subtract()

Output

A-B= [4, 1]
B-C= [3, 2]

Here, we have used the subtract() method to compute the subtraction between A and B & B and C respectively.

Example 2: Use of Swift subtract() and Ranges

Output

[3, 1, 4]

Here, 1...14 represents a set of numbers that ranges from 1 to 4 and is assigned to total.

Finally, we have computed the subtraction between total and [2,5,6].
