What is the output of this Swift code?

func minMax(numbers: [Int]) -> (min: Int, max: Int) {
    var currentMin = numbers[0]
    var currentMax = numbers[0]
    for number in numbers[1...] {
        if number < currentMin { currentMin = number }
        if number > currentMax { currentMax = number }
    }
    return (currentMin, currentMax)
}

let result = minMax(numbers: [3, 7, 2, 9, 4])
print(result.min, result.max)

A2 9

B3 7

C9 2

DError: tuple elements not accessible

Step-by-Step Solution

Solution:

Step 1: Trace min and max calculation
Start with first number 3 as min and max. Iterate over 7, 2, 9, 4 updating min to 2 and max to 9.
Step 2: Access tuple elements by name
Returned tuple has named elements min and max, so result.min is 2 and result.max is 9.
Final Answer:
2 9 -> Option A
Quick Check:
min = 2, max = 9 [OK]

Quick Trick: Tuple elements accessed by name like properties [OK]

Common Mistakes:

Confusing min and max values
Trying to access tuple elements by index instead of name
Forgetting to start loop from second element
