(B2). Implement a randomized Skip-List with operations Insert(), Delete() and Search(). Your program should read from the input file just like in (BI). Print out the skip-list using the format given below 16 16 71 91 2 16 71 89 91 16 89 2 10 15 16 31 71 86 89 91 96 86 96

Given two integers start and end, where end is greater than start, write a recursive Java method that returns the sum of the integers from start through end, inclusive.

Tracing the Recursion. Observe the recursive solution provided below and answer the followingquestions:1. Which line(s) of this program define(s) the base case of the binary() method?2. Which line(s) of this program include recursive call(s)?3. Trace the recursion below. You must show the tracing step by step (write themdown); otherwise – little to no credit!4. At what step of your recursion tracing did you hit the base case?5. What is the final output of this code?

Need help with this python recursive basic pathfinding question. I have the layout of the code but I need help filling in the parts that say "pass" and I need the output of the code to match the sample run below. Our goal is to find a path (not the best path, but just any path) from A to Z.  You see that the green path is not the shortest but it does let us navigate from start to finish.  (The picture below) First, we need to know A and Z, our starting and ending points.  We'll pass these into our function.   I'm going to use a dictionary to represent this graph.  Each node (vertex, circle) will have a name, in this case "A" and "Z" were the names of the nodes, but in the generated maps I'm going to use "Node 1", "Node 2", "Node 3", etc.     Here is an example web_map web_map = { 'Node 1': ['Node 3', 'Node 2'],  'Node 2': ['Node 1', 'Node 4'],  'Node 3': ['Node 1'],  'Node 4': ['Node 2'] } Node 1 is connected to 2 and 3 for instance, and then also note that Node 3 is connected back to…
