# plus_two Given 2 int lists, each length 2, return a new list length 4 containing all their elements. ``` plus_two([1, 2], [3, 4]) -> [1, 2, 3, 4] plus_two([4, 4], [2, 2]) -> [4, 4, 2, 2] plus_two([9, 2], [3, 4]) -> [9, 2, 3, 4] ``` This exercise was taken from [codingbat.com](https://codingbat.com/prob/p180840) and has been adapted for the Python language. There are many great programming exercises there, but the majority are created for Java. ## Starter Code ```python from typing import List def plus_two(a: List[int], b: List[int]) -> List[int]: pass result = plus_two([1, 2], [3, 4]) print(result) ``` ## Tests ```python from main import plus_two def test_plus_two_1(): assert plus_two([1, 2], [3, 4]) == [1, 2, 3, 4] def test_plus_two_2(): assert plus_two([4, 4], [2, 2]) == [4, 4, 2, 2] def test_plus_two_3(): assert plus_two([9, 2], [3, 4]) == [9, 2, 3, 4] ```
