Try to solve 3 Golang interview questions and Go interview questions below. Hints can help you find answers to questions you are having trouble with.

## 1. Merge Names

Slices

Easy

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.

•   Each slice has distinct names: Wrong answer
•   Each slice has duplicate names: Wrong answer
•   Slices have some names in common: Wrong answer

Arithmetic

Easy

Implement the function findRoots to find the roots of the quadratic equation: ax2 + bx + c = 0.

The roots of the quadratic equation can be found with the following formula: For example, the roots of the equation 2x2 + 10x + 8 = 0 are -1 and -4.

## 3. Numeric Input

Interfaces

Easy

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{}
fmt.Println(input.GetValue())``````
