Sample Solution:

Swift Code:

func newarray(_ arra: [Int]) -> [Int] {
    var new_arra = arra
    
    if new_arra.first! > new_arra.last!
     {
        new_arra[1] = new_arra.first!
        new_arra[2] = new_arra.first!
     } 
    else 
     {
        new_arra[0] = new_arra.last!
        new_arra[1] = new_arra.last!
     }
    return new_arra
}

print(newarray([1, 2, 3]))
print(newarray([-5, -4, 0]))
print(newarray([12, 14, 16]))

Sample Output:

[3, 3, 3]
[0, 0, 0]
[16, 16, 16]
