It is possible in this example to show that a language can be recognized by a deterministic queue automaton if the language is Turing-recognizable.
For computation, we first need to transfer the input string on queue. We do so by using right moves and pushing each read symbol. Then, we simulate the right move of TM with pull of the rightmost elements of the queue and pushing the new symbol according to transition function back to queue. On the other hand, the left reset of TM is simulated using pushing until we reach special symbol which denotes the left-hand end of tape. We push and pull until we are at the right position. Therefore, we can intuitively simulate left-reset Turing machines.

c) 2^32 times as many values can be represented.
Explanation:
It's funny, this problem comes from a real-life situation, except it wasn't really foreseen :-) And we will encounter a similar problem in less than 20 years.
The difference in terms of storage capacity from 32-bit integers and 64-bits integers is huge.
A 32-bit integer can store (signed) numbers up to 2,147,483,647. (so over 2 BILLIONS)
A 64-bit integer can store (signed) numbers up to 9,223,372,036,854,775,807 (9 BILLIONS of BILLONS)
