About the test

The Go/Golang online test assesses candidates' knowledge of programming in Go language and their ability to leverage commonly used built-in functions.

It's an ideal test for pre-employment screening. A good Go developer needs to be able not only to solve problems using Go as the programming language but also recognize when to take advantage of its rich set of built-in functions.

This test requires candidates to be able to solve coding problems in Go and find and fix bugs in Go programs.

Slices

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.

Arithmetic

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.
