This problem has been solved! see the answerwwe assume that all languages are over input alphabet {0,1}. also, we assume that a turing machine can have any fixed number of tapes. sometimes restricting what a turing machine can do does not affect the class of languages that can be recognized the restricted turing machines can still be designed to accept any recursively enumerable language. other restrictions limit what languages the turing machine can accept. for example, it might limit the languages to some subset of the recursive languages, which we know is smaller than the recursively enumerable languages. here are some of the possible restrictions: 1. limit the number of states the tm may have.2. limit the number of tape symbols the tm may have.3. limit the number of times any tape cell may change.4. limit the amount of tape the tm may use.5. limit the number of moves the tm may make.6. limit the way the tape heads may move. consider the effect of limitations of these types, perhaps in pairs. then, from the list below, identify the combination of restrictions that allows the restricted form of turing machine to accept all recursively enumerable languages. a) allow the tm to run for only n2 moves when the input is of length n. b) allow the tm to use only 2n tape cells when the input is of length n. c) allow a tape cell to change its symbol only once. d) allow the tm to run for only 2n moves when the input is of length n. can you explain to me stepwise to learn tharougly

Write a program that keeps asking the user for new values to be added to a list until the user enters 'exit' ('exit' should not be added to the list). these values entered by the user are added to a list we call 'initial_list'. then write a function that takes this initial_list as input and returns another list with 3 copies of every value in the initial_list. finally, inside print out all of the values in the new list. for example: input: enter value to be added to list: a enter value to be added to list: b enter value to be added to list: c enter value to be added to list: exit output: a b c a b c a b c note how 'exit' is not added to the list. also, your program needs to be able to handle any variation of 'exit' such as 'exit', 'exit' etc. and treat them all as 'exit'.
