Write a method countmultiples that could be added to the inttree class from lecture and section. the method returns a count of the number of multiples of a particular value in the binary tree. given a number n, a value m is considered a multiple of n if it can be expressed as (k * n) for some integer k. for example, suppose that an inttree variable tree stores a reference to the following tree:

Which best describes the role or restriction enzymes in the analysis of edna a. to break dna into fragments that vary in size so they can be sorted and analyzed b. to amplify small amounts of dna and generate large amounts of dna for analysis c. to purify samples of dna obtained from the environment so they can be analyzed d. to sort different sizes of dna fragments into a banding pattern that can be analyzed
