Write MapReduce algorithms for computing the following operations on bags R and S: (a) Bag Union, defined to be the bag of tuples in which tuple t appears the sum of the numbers of times it appears in R and S. (b) Bag Intersection, defined to be the bag of tuples in which tuple t appears the minimum of the numbers of times it appears in R and S. (c) Bag Difference, defined to be the bag of tuples in which the number of times a tuple t appears is equal to the number of times it appears in R minus the number of times it appears in S. A tuple that appears more times in S than in R does not appear in the difference.

it is much more convenient for the consumer to order something online, rather than going to a store. it saves them time and money for them, especially if that item is not accessed easily.

assuming you are in the home page.

given the lack of choices, i'm gonna wing it and say that pushing your car off a cliff might not be the best idea. your car might sustain damage from the fall and will probably result in the car being too damaged to jump start.

if that's not good enough, avoid filling the car with bees. bees might get agitated when trapped or during the moving process, and might result in death or painful stings that will make jump starting your car very difficult. but in the event that you do choose to fill your car with bees, remember to wear protective gear!
