A set of three numbers {a, b, c} is given. We are allowed to transform it in the following way: pick any two of them, say a and b, and replace them with two numbers (√ 3 a + b)/2 and (−a + √ 3 b)/2. Is it possible to obtain the triple {2, − √ 3, 1 − √ 3} from the triple {2, √ 3, √ 3/3} by performing a sequence of such operations? Justify your answer.

Java please. Given a sequence of unsorted numbers, determine how badly out of order they are. Write a program that, for any given sequence of unique natural numbers, will compute the 'distance' between that original ordering and the same set of numbers sorted in ascending order. The distance should be computed by calculating how far displaced each number is in the original ordering from its correct location in the sorted list and summing those results. For instance, given the list...
