Task

Brainfuck Compiler

Write a Java program that runs a program written in the language Brainfuck

Input: Brainfuck line of instructions

++++++++[>++++[>++>+++>+++>+<<<<-]>+>+>->>+[<]<-]>>.>---.+++++++..+++.>>.<-.<.+++.------.--------.>>+.

Output: a string containing the output of a executed program Hello World!

Additional requirements:

The implementation of the program should consist of 2 stages:

1. Compilation. An input line is used to construct a data model using the principles OOP and design patterns.
2. Execution. To execute the program according to the constructed model, without access to the original line.

The input command , does not need to be supported

Write the necessary Unіt and functional tests.

Java 8, Gradle, Github.

BrainFuck commands:

> increment the data pointer (to point to the next cell to the right).

< decrement the data pointer (to point to the next cell to the left).

+ increment (increase by one) the byte at the data pointer.

- decrement (decrease by one) the byte at the data pointer.

. output the byte at the data pointer.

, accept one byte of input, storing its value in the byte at the data pointer.

[ if the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command.

] if the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command.
