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.
Answer:
c. StringBuilder
Explanation:
An alternative to the String class would be the StringBuilder Class. This class uses Strings as objects and allows you to mix and match different strings as well as adding, removing, implementing, and modifying strings themselves as though they were similar to an array. Unlike the string class StringBuilder allows you to modify and work with a combination of strings in the same piece of data as opposed to having various objects and copying pieces which would take up more memory.
Answer:
B.O(n).
Explanation:
In an ADT graph the method addEdge uses an Array of list.So in the worst case and the worst will be when the list already has n elements in it.
So to add an edge we have to iterate over the list upto nth element and then add the edge after that.So it has to travel over n elements.
So we can say that the answer is O(n).
