give a turing machine with input alphabet {a, b}that on input w halts with wrwritten on its tape. (ex: ⊢abbb turns to ⊢bbba)

Answers

Answer 1

Turing machine that does what you're looking for: 1. Start in state q0, with the input string w written on the tape and the head pointing to the first symbol. 2. Scan the tape from left to right, looking for the last symbol that is not equal to b. Once you find it, move the head back one position to the left and transition to state q1.


3. In state q1, replace the symbol under the head with a b, move the head one position to the right, and transition back to state q0.
4. Repeat steps 2-3 until there are no more symbols that are not equal to b on the tape.
5. Once the machine has scanned the entire input string and replaced all non-b symbols with b's, transition to state q2 and halt. At this point, the final string on the tape should be the original input w followed by its reversal, i.e. w followed by w written backwards.

Here's a formal description of the Turing machine in terms of its states, transitions, and actions:

Q = {q0, q1, q2}
Σ = {a, b}
δ(q0, a) = (q0, a, R)
δ(q0, b) = (q0, b, R)
δ(q0, ⊔) = (q1, ⊔, L)
δ(q1, a) = (q1, b, R)
δ(q1, b) = (q1, b, L)
δ(q1, ⊔) = (q0, ⊔, R)
δ(q0, ⊔) = (q2, ⊔, H)

Here, Q is the set of states, Σ is the input alphabet, δ is the transition function, and (q, a, d) means "if the machine is in state q, reads symbol a, and is currently moving in direction d, then transition to a new state and write a new symbol in the current cell while moving the head in a new direction". The special symbol ⊔ represents a blank cell on the tape, and H means "halt". The machine starts in state q0, reads the input symbols from left to right while moving right on the tape, and halts in state q2 once it has finished processing the input.
A Turing machine that accepts an input alphabet {a, b} and halts with the reversed input (w) written on its tape can be constructed using the following transition rules:

1. From the initial state (q0), if the input is "a", replace it with "X" and move right, going to state q1.
2. From q1, if the input is "a" or "b", move right (stay in q1) until you find an empty cell (blank tape).
3. When you find an empty cell, move left and enter state q2.
4. In q2, if the input is "a", replace it with a blank cell, move left, and enter state q3.
5. In q2, if the input is "b", replace it with a blank cell, move left, and enter state q4.
6. From q3 (if the last character was "a") or q4 (if the last character was "b"), move left until you find "X". Then, move right and enter state q5.
7. In q5, if you find an "X", move right and go back to step 2.
8. If you find a blank cell while in q5, it means the input has been fully reversed. Replace "X" with a blank cell and halt.

This Turing machine, when given an input w (e.g., ⊢abbb), will halt with the reversed input (wr) written on its tape (e.g., ⊢bbba).

A computer-simulated mailbox that stores email messages. Mailboxes are saved on a disc as a message file or a message database.

A delegate is someone who has been granted permission by another user to access and manage their mailbox, including sending and responding to email messages on their behalf.

When you grant delegate access to another person, you are giving them the ability to access specific folders within your mailbox and perform specific actions, such as reading, sending, and deleting email messages.

Assignee, client, and manager are not terms typically used in the context of delegate access in email systems.
