Sample Solution:

Swift Code:

func first_last(_ a: [Int], _ b: [Int]) -> Bool {
    guard a.count > 0, b.count > 0 else 
    {
        return false
    }
    
    if a.first == b.first || a.last == b.last
    {
        return true
    } 
    else
    {
        return false
    }
}
print(first_last([1, 2, 3], [5, 1]))
print(first_last([1, 2], [4, 2]))
print(first_last([1, 2, 3, 1], [-1, 3, 5]))

Sample Output:

false
true
false
