Construct a turing machine that accepts the language {ww^R : w <- {a,b}+}, where w^R denotes w superscripted R - reverse of w. For example, if

w = abb


w^R = bba
ww^R = abbbba

Notations used for denoting a turing machine transition are as follows.

(StartState, SymbolRead) --> (EndState, SymbolWritten, MovementDirection)

* Movement Directions are denoted by R (right) and L (left).
* E is used to denote NULL symbol (or absense of symbol in a tape cell).
* $ denotes a marker symbol.

* You can construct ...

Solution Summary

Solution gives a transition list for the given turing machine, using which you can easily construct a graphical representation of it.
