Sample Solution:

Swift Code:

func first_last_5( _ arra:[Int]) -> Bool {
    if arra.first == 5 || arra.last == 5 
    {
        return true
    } 
    else 
    {
        return false
    }
}
 print(first_last_5([1, 2, 5]))
print(first_last_5([5, 1, 2, 3, 4]))
print(first_last_5([5, 6, 1, 2, 5]))
print(first_last_5([1, 2, 6, 5, 3, 7]))

Sample Output:

true
true
true
false
