Implement the uniqueNames function. When passed two slices of names, it will return a slice containing the names that appear in either or both slices. The returned slice should have no duplicates.

For example, calling uniqueNames([]string{"Ava", "Emma", "Olivia"}, []string{"Olivia", "Sophia", "Emma"}) should return a slice containing Ava, Emma, Olivia, and Sophia in any order.

User interface contains NumericInput control, which accepts only digits.

Extend NumericInput structure so that:

• It implements UserInput interface.
• Add(rune) should add only decimal digits to the input. Other runes should be ignored.
• GetValue() should return the current input.

For example, the following code should output "10":

var input UserInput = &NumericInput{}
input.Add('1')
input.Add('a')
input.Add('0')
fmt.Println(input.GetValue())
