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

then

w^R = bba

ww^R = abbbba

#### Solution Preview

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 ...
