1) How many possible ways could a list of n values be ordered, i. e., how many ordering permutations are there? 2) Argue that if you know a list’s order permutation, sorting is easy (linear time), and conversely, if you know the steps to sort the list, you can easily generate the order permutation. 3) Given this, argue that sorting can’t be easier than finding the order permutation.

State whether weight is a function of height for the six students and explain. a. yes, height is a function of weight because two students weigh 165 pounds but have different heights. b. no, height is not a function of weight because two students weigh 165 pounds but have different heights. c. yes, weight is a function of height because for each value of height there is one corresponding value of weight. d. no, weight is not a function of height because there is not enough data to determine a function.
