> Esoteric programming languages (esolang) are designed to test the boundaries of computer programming design, as proofs of concept, as software art, as a hacking interface or simply as a joke. One such esoteric language is `Brainfuck`. It was created by Urban Müller in 1993. It is a minimalist language consisting of 8 simple commands. It is Turing complete, but is not intended for practical use. It exists to amuse and challenge programmers.
### Instructions
### Instructions
Write a `Brainfuck` interpreter program.
Write a `Brainfuck` interpreter program.
The source code will be given as first parameter.
The code will always be valid, with less than 4096 operations.
The source code will be given as the first parameter, and will always be valid with fewer than 4096 operations.
`Brainfuck` is a minimalist language. It consists of an array of bytes (in this exercice 2048 bytes) all initialized with zero, and with a pointer to its first byte.
Your `Brainfuck` interpreter will consist of an array of 2048 bytes, all initialized to 0, with a pointer to the first byte.
Every operator consists of a single character :
Every operator consists of a single character:
- '>' increment the pointer
- `>`: increment the pointer.
- '<' decrement the pointer
- `<`: decrement the pointer.
- '+' increment the pointed byte
- `+`: increment the pointed byte.
- '-' decrement the pointed byte
- `-`: decrement the pointed byte.
- '.' print the pointed byte on standard output
- `.`: print the pointed byte to the standard output.
- '[' go to the matching ']' if the pointed byte is 0 (loop start)
- `[`: if the pointed byte is 0, then instead of moving onto the next command, skip to the command after the matching `]`.
- ']' go to the matching '[' if the pointed byte is not 0 (loop end)
- `]`: if the pointed byte is **not** 0, then instead of moving onto the next command, move back to the command after the matching `[`.
