This question relies only on creating and manipulating Node objects. The Node class code is shown (partially): public class Node { public int data; public Node next; <more code would be here> } Assume you have appropriate constructors to create Node objects with either default (0, null) values or user-assigned values. You may create as many Node objects as you want to solve the following problems, but you cannot create objects of other classes. You do NOT need to create complete methods – only provide as much code as is needed to accomplish each task. 3a) Provide code to create a linked sequence of nodes containing the values 1, 2, 3, 4, 5. The nodes should be in this order, with the “front” node containing the value 1, and the node farthest away from ““front” containing the value 5. 3.b) Describe the form of the linked structure you have created (how many nodes, what order they have, where front and cursor are located, etc.).

EXERCISE 1.3.2: Unions and intersections of sequences of sets. Use the definition for A; to answer the questions. For i = Z¹, A₁ is the set of all positive integer multiples of i. (a) Describe the following set using set builder notation: 5 i=1 Aį (b) Describe the following set using roster notation: (U₁₂) ME An{ €Z: 1 ≤ x ≤ 20}
Express each set below using the roster method. Write the answer as a set using curly braces. Write all elements in increasing order using commas. Be sure to include the curly braces. Do not include any spaces in your answers. {x € Z+ | a? < 16} {x € Z | x² < 9} {x €N|a? < 9}

Implementation of largest-cover difference #23@title Implementation of largest-cover difference def rectangle_difference(r, t): "Computes the rectangle difference rt, and outputs the result as a list of rectangles." assert len(r) == len(t), "Rectangles have different dimensions" ### YOUR SOLUTION HERE In the above code, we notice how it paid off to encapsulate intervals in their own abstraction. Now that we need to reason about rectangles, we do not need to get bogged down into complicated considerations of how to perform difference; the comparisons between endpoints are all done in the context of intervals, where it is easier to reason about them. It is often the case that problems become easy, once you think at them in the appropriate context. It is much easier to develop the code for the difference of intervals, as we have done, and then move on to difference of rectangles, rather than trying to write code for rectangle difference directly. The result is also far more elegant. # Let…
