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.

Implement the function findRoots to find the roots of the quadratic equation: ax2 + bx + c = 0. If the equation has only one solution, the function should return that solution as both results. The equation will always have at least one solution.

The roots of the quadratic equation can be found with the following formula: A quadratic equation.

For example, the roots of the equation 2x2 + 10x + 8 = 0 are -1 and -4.

Go Interfaces Public New

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())
