Suppose we are given two n-element sorted sequences A and B that should not be viewed as sets (that is, A and B may contain duplicate entries). (a) Describe an O(n)-time algorithm^2 for computing a sequence representing the set A Intersection B. (b) If the sequences A and B are instead unsorted, what is asymptotic time complexity of the most efficient algorithm that you can construct that computes A Intersection B? Describe this algorithm.

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
