Question: Transform the TM below that accepts words over the alphabet = { a , b } with an even number of a ' s and

Transform the TM below that accepts words over the alphabet

= {a, b}

with an even number of

a'

s and

b'

s in order that the output tape head is positioned over the first letter of the input, if the word is accepted, and all letters a should be replaced by the letter

x .

For example, for the input aabbaa the tape and head at the end should be:

[x] x b b
