[Solved] What is the output of the following Swift code?let setA: Set = [1, 2, 3, 4] let setB: Set = [3, 4, 5, 6] let result = setA.union(setB) print(result.sorted()) | Swift

Swift - Collections

What is the output of the following Swift code?

let setA: Set = [1, 2, 3, 4]
let setB: Set = [3, 4, 5, 6]
let result = setA.union(setB)
print(result.sorted())

A[1, 2, 3, 4]

B[1, 2, 3, 4, 5, 6]

C[3, 4, 5, 6]

D[1, 2]

Step-by-Step Solution

Solution:

Step 1: Understand the union operation on setA and setB
Union combines all unique elements from both sets: 1, 2, 3, 4, 5, 6.
Step 2: Sorting the result
The sorted() method returns the elements in ascending order: [1, 2, 3, 4, 5, 6].
Final Answer:
[1, 2, 3, 4, 5, 6] -> Option B
Quick Check:
Union result sorted = [1, 2, 3, 4, 5, 6] [OK]

Quick Trick: Union merges all unique elements; sort to see ordered list [OK]
