a. Write out – draw the diagram with states and arrows – for a one-tape deterministic Turing machine that accepts the language over {a,b, !}   L = {w!x!w: x,w in (a|b)*} = {!!, a!!a, …, aba!a!aba, … bbba!aa!bbba, ….

(strings in L have three parts divided by !.   First and third parts must be equal.)

b. Write out the sequence of configurations for some string of length at least 5 (can be in L or not in L)

c. What is the big-oh O of your TM?   explain

Solutions

Expert Solution

In first part ,we have to construct deterministic TM for L={w!x!w , w,x belongs to (0,1)*}.TM is given above.

In second part,we simulate for w=ab!a!ab,and configration of TM are given above.

In third part,we need to find time complexity i.e.O(n)^2.

Trace (either draw a picture or write words and arrows) the path of sound from the outer ear to interpretation by the brain, detailing what each step in the pathway is generally responsible for. This does not have to be extremely detailed (e.g. cell types), but should show pathways and the function of specific nuclei & brain areas.

. Draw a diagram showing the demand and supply for aluminum in the United States. Assume the United States can import as much as it wants at the world price of aluminum without causing the price to increase; and assume that the world price is lower than the U.S. equilibrium price. Be sure to indicate on your graph the quantity of aluminum imported. (Feel free to use hypothetical numbers.) Be sure to briefly describe your diagram in words. 2. Now...
