Programming Consider the task of checking to see if a graph contains a cycle. This task can, of course, be accomplished with a recursive DFS algorithm. Unfortunately, in very large graphs it is not appropriate to use recursion to explore, because it requires a vast amount of system memory (to track each recursive call). Implement a method for checking for a cycle in a graph using the DFS algorithm WITHOUT using recursion. Assume that the Stack ADT is available and you are using the standard Graph ADT discussed in class. (Huge Hint: start by thinking about BFS, and how it works without recursion.)   Assume a marked variable exists and has been set up to be the size of the graph and with every index set to false. public static boolean[] marked;public static boolean hasCycle(Graph G, int start) { Stack s = new Stack(); //TODO: implement this method.

We want to calculate item-item similarity for item-based collaborative filtering using users’ ratings on various items. Since most items are rated by only a few users, we have sparse vector representations for each item. What are the appropriate measures to calculate item similarity in this case?

Instructions: Match each step name with the description of step of the EBP process using Brown & Ecoff’s 8A’s model with the new intervention of hourly rounding and script of offering possessions, potty-ing, pain assessment, and positioning.  Background: Patient falls are serious events for patients, staff, and hospitals. The average cost for a fall with injury is $14,000 and increases the hospital stay an average of 6.3 days (Sentinel Event Alert, 2015). The simple act of hourly rounding has been suggested as a way to increase patient satisfaction, decrease call light usage, and decrease patient falls. This is a significant problem affecting the patient, nurse, and organization. Patient safety is a top priority for all hospitals and the cost of a patient injury resulting from a fall can be tremendous. Meade et al. (2006) found that hourly rounding can increase patient satisfaction and decrease call light use as well as patient falls. The best practice for hospitalized patients would be to implement hourly rounding. What is the process in finding the best practice to decrease patient falls through hourly rounding during hospitalization? Recall your own EBP clinical proposal project and the steps necessary to complete your EBP change project proposal assignment.

 Suppose x and y have each been assigned a list.  Write Python code that creates a new list w that contains each top-level element of x that occurs exactly twice as a top-level element of y.  You can assume the lists have already been created and assigned to x and y, but you must create the new list w, as described above.
