 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:
+
 - `>`: increment the pointer.
 - `<`: decrement the pointer.
 - `+`: increment the pointed byte.
 - `-`: decrement the pointed byte.
-- `.`: print the pointed byte to the standard output.
-- `[`: if the pointed byte is 0, then instead of moving onto the next command, skip to the command after the matching `]`.
-- `]`: if the pointed byte is **not** 0, then instead of moving onto the next command, move back to the command after the matching `[`.
-
-Any other character is a comment.
+- `.`: print the pointed byte to standard output.
+- `[`: If the byte at the current pointer is 0, skip forward to the command after the matching `]`.
+- `]`: If the byte at the current pointer is not 0, jump back to the command after the matching `[`.
+- Any other character is treated as a comment and ignored.
