Re: Questions on turing machine problems

1) I'm trying to understand the following problem: let M_1 and M_2
two turing machines with common input alphabet and a given string x. Is
there a particular step in which the two machines will write the same
symbol on the tape?

These TMs will probably write the same symbol on the tape at
/every/ step - unless you explain in what way they differ.
