Question
SO I NEED HELP WITH THE FOLLOWING ASSIGNMENT. IT IS PYTHON RELATED AND WE ARE USING PYTHON 3.3. IT USES TREES AND RECURSION. THE INSTRUCTIONS ARE GIVEN BELOW:
I WILL REWARD 5000 POINTS AND WILL ADD MORE POINTS IF THINGS LOOK GOOD (GUARANTEED). I NEED THE SOLUTION TO THIS ASAP.
LOOK AT THE UPLOADED FILE.
THANKS A LOT.

Regular expressions (abbreviated to ngcx, the pronunciation of which gives rise to endless flame wars... ) are used in various programming languages and utilities to match entire classes of strings. This assignment will give you experience modelling a regular expression as a tree, and detecting which strings match a given regular expression. We won't favour any particular regex language or utiUty, such as Python, Java, or Linux's grep. instead, we'll use a stripped-down simplified regular expression form that contains all the essential principles. In particular, you are not permitted to import Python's regular expression module re into any file you submit. We'll only be deaUng with a ternary alphabet, i.e., {0, 1, 2}. Generalizing to an arbitrary alphabet is straightforward, but doesn't buy us much for the purpose of this assignment. The elementary regex symbols we'll use can be easily typed in Python source code. A regex (over ternary alphabet {0, 1, 2}) is a nonempty string made up of the following symbols. '0' called zero '1' one '2' two 'e' pronounced "ee" or "epsilon" 'I' bar ',' dot '*' star '(' left parenthesis, or left ')' right parenthesis, or right There are several rules determining that a string made up of these symbols is a vaUd regular expression: 1. There are 4 regexes of length one. They are: '0' '1'
