Correct answer will be upvoted else downvoted. Computer science. Child Ehab has a piece of Cut and Stick with an exhibit an of length n composed on it. He intends to snatch some scissors and do the accompanying to it: pick a reach (l,r) and cut out each component al, al+1, ..., ar in this reach; stick a portion of the components together in a similar request they were in the exhibit; end up with different pieces, where each piece contains a portion of the components and each component has a place with some piece. All the more officially, he segments the arrangement al, al+1, ..., ar into aftereffects. He thinks a dividing is lovely if for each piece (aftereffect) it holds that, assuming it has length x, no worth happens rigorously more than ⌈x2⌉ times in it. He didn't pick a reach yet, so he's pondering: for q ranges (l,r), what is the base number of pieces he really wants to parcel the components al, al+1, ..., ar into with the goal that the dividing is delightful.…

Subject: artificial intelligence Forward chaining and Backward chaining Suppose that the coding resulting from the acceptance of knowledge is as follows: A1 = body temperature >= 38°C A2 = cough A3 = cold A4 = persistent cough especially at night A5 = breath sounds P1 = common fever P2 = normal cough P3 = influenza / viral infection P4 = whooping cough P5 = respiratory tract infection The rules on the knowledge base include: R1 : IF A1 THEN P1 R2 : IF A2 THEN P2 R3 : IF P1 and (P2 or A3) THEN P3 R4 : IF P3 and A4 THEN P4 R5 : IF P3 and A5 THEN P5 The facts obtained from the user are that the fever, cough, and cough are more frequent at night (A1, A2, A4 → true). Explain the steps to get a conclusion if the inference technique used is: a. Forward chaining b. Backward chaining
