write a
Where Pz(x,y) is point z with x and y coordinates in the 2D space.
Write a method searchList that recursively searches the linked list of point objects for a specified point w with x1 and y1 cooredinates: Pw(x1, y1). Method searchList should return true if it is found; otherwise, false should be returned. Use your method in a test program that creates the above list. The program should prompt the user for a value to locate in the list. For example: Enter two integer values representing the x and y coordinate of the point you want to look for in the list:
3 4
This point is found
Anothet example: Enter two integer values representing the x and y coordinate of the point you want to look for in the list:
0 1
The point does not exist.

- There is a data structure called a drop-out stack that behaveslike a stack in every respect except that if the stack size is n,then when the n+1 element is pushed, the first element is lost.Implement a drop-out stack using links.arrow_forward1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 Write a function to delete a node (except the tail) in a singly linked list, given only access to that node. Supposed the linked list is 1 - 2 - 3 -> 4 and you are given the third node with value 3, the linked list should become 1 -> 2 -> 4 after calling your function. import unittest class Node: definit__(self,x): self.val x self.next = None def delete_node (node): if node is None or node.next is None: raise ValueError node.val node.next.val node.next = node.next.next class TestSuite(unittest.

- unique please Your task for this assignment is to identify a spanning tree in one connected undirected weighted graph using C++. Implement a spanning tree algorithm using C++. A spanning tree is a subset of the edges of a connected undirected weighted graph that connects all the vertices together, without any cycles. The program is interactive. Graph edges with respective weights (i.e., v1 v2 w) are entered at the command line and results are displayed on the console. Each input transaction represents an undirected edge of a connected weighted graph. The edge consists of two unequal non-negative integers in the range 0 to 9 representing graph vertices that the edge connects. Each edge has an assigned weight. The edge weight is a positive integer in the range 1 to 99. The three integers on each input transaction are separated by space. An input transaction containing the string “end-of-file” signals the end of the graph edge input. After the edge information is read, the process…arrow_forwardA student implementing a linked list wrote this method: bool LinkedList::Remove(int e) { for (Node *ptr _head; ptr != nullptr; ptr = ptr->next): %3D 3 1 if (e ptr->element) { %3D%3D 4. Node *deleteMe; deleteMe = ptr->next; ptr->element ptr->next delete deleteMe; ptr->next->element; ptr->next->next; 8. 9. 10 return true; } } return false; 11 12 13 14 } The student tested it with this linked list: head nullptr Strangely he found that it worled perfectly except it crashed with a segmentation fault for only one value. What was the value of e that made it crash? What was the number of the line where it crashed?arrow_forwardHow to announce a Linked List Node with three characters in C language, same as the example shown in teaching materials For example is the following figure. EAT O a. struct Node { char *EAT[3]; struct Node next; } Node; O b. struct { Char Three; Link *Next; }; O c. typedef Linked Node { Character EAT; Arrow Link; O d. struct Node { char Three; Arrow Link; }; O e. typedef structure Node { char Name[3]; structure Node *Next; }; O f. structure List Node { Three Character; Link; } O g. typedef struct Node { char name[3]; struct Node *next; } node_C; Oh. typedef struct Node { char EAT; struct *Next; };arrow_forward
- Implement an algorithm to delete a node in the middle (i.e., any node butthe first and last node, not necessarily the exact middle) of a singly linked list, given only access tothat node.EXAMPLElnput:the node c from the linked list a->b->c->d->e->fResult: nothing is returned, but the new linked list looks like a ->b->d->e->farrow_forwardIf a Stack is most optimally derived from a Singly Linked List, which node of the Linked List should be pointed to or will be referred to as the Top of the stack and why?arrow_forwardThere is a data structure called a drop-out stack that behaveslike a stack in every respect except that if the stack size is n,then when the n+1 element is pushed, the first element is lost.Implement a drop-out stack using linksarrow_forward
- IN JAVA LANGUAGE ALL INFORMATION IN PICTURES FIND MIN OF A BST CALL ON A RECURSIVE FINDMIN_R THAT WILL RETURN THE SMALLEST ELEMENT IN A BST THANK YOU!!!!!!!!!!!arrow_forwardGiven a stack, a function is consecutive takes a stack as a parameter and thatreturns whether or not the stack contains a sequence of consecutive integersstarting from the bottom of the stack (returning true if it does, returningfalse if it does not). For example:bottom [3, 4, 5, 6, 7] topThen the call of is_consecutive(s) should return true.bottom [3, 4, 6, 7] topThen the call of is_consecutive(s) should return false.bottom [3, 2, 1] top The function should return false due to reverse order.
