This is a simple solution proposed to the Hell-Triangle problem.
You can run it as the Maven project or through the class Application, entering a text that represents a triangle in the follow format:
[[6],[3,5],[9,7,1],[4,6,8,4]]
Or you can use (and even increment) the Junit Theories in the class HellTriangleTest.
Attemption: This project use the Lombok library (https://projectlombok.org/). Some IDE'S (like IntelliJ) will requiere the lombok plugin instalation for compile the Getters, Setters and Constructors at real time.
