B. A binary tree that has a deepest node at depth 2 log N.

C. A binary tree that has a deepest node at depth 4.1 log N.

a social news website is an internet website that features user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the slashdot and fark websites, administrators decide which articles are selected for the front page. on reddit and digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a social networking function, in that users can set up a user profile and follow other users' online activity on the website.

The best answer is c) the main() methodfor java, that will be the main starting/entry point. the other choices are generally irrelevant.a java program need not access a firewall, especially if it is designed to work offline. a firewall only deals with networking; it will not be relevant for all java programs.microsoft excel is not relevant for all java programs.a colon is too general.

Public static int mystery(int a[], int x) { int c = 0; for(int i = 0; i < a.length; i++) { if (a[i] == x) c++; } return c; }the method counts how many times an integer shows up in an integer array.the c variable is declared in the method to keep track of how many times the certain value has shown up.the for-loop loops through the entire array.the line if (a[i] == x) c++; checks if each element of the array is equal to the inputted integer to check. for each number in the array that is equal to the inputted integer x, the c variable will be incremented by 1. otherwise it will do nothing.then c is returned at the end of the loop.for example, if we have, in the main method with the mystery method coded in the class: int arraytest[] = {2, 23, 23, 23, 3}; int testme = 23; int count = mystery(arraytest, testme); system.out.println(count); then the print out will be 3 because there are three 23s in that array.

Write a method that takes in an array of point2d objects, and then analyzes the dataset to find points that are close together. be sure to review the point2d api. in your method, if the distance between any pair of points is less than 10, display the distance and the (x,y)s of each point. for example, "the distance between (3,5) and (8,9) is 6.40312." the complete api for the point2d adt may be viewed at ~pf/sedgewick-wayne/algs4/documentation/point2d.html (links to an external site.)links to an external site.. try to write your program directly from the api - do not review the adt's source code.
