Parenthesis Language
The following extended Turing machine using 4 characters, checks strings of parentheses for correct matching.
In the implementation below, '(' = white, ')' = black, which are entered as 0 and 1 respectively.
These are enclosed in '#' = red, entered as 9, and are converted to '*' = green, when balanced.
Instructions shown as '?' indicate that further processing could be done, or the head re-positioned, especially with unbalanced parenthesis strings.
To get the best from this interactive module, you will need to download the free CDF player from the Wolfram Inc. website.
