HINT: For i = 1 , . . . ,n, let S[i] be the max sum ending with A[i] while allowing size-1 gaps. Derive a recurrence for S[i] Problem 4. Max sum with 1-gaps Given a length- n array of integers A[1n], we would like to find maximum sum which could be obtained by adding elements in a subsequence of A if we are allowed to start anywhere in A but once we start, we can either take the element after the previously selected element or the one after, i.e, gaps of length at most 1 are allowed in the subsequence. More formally, given A find the maximum S such that there is an integer 0mn and indices 1i1<.

I'm creating a skip list program for my Algorithms and Advanced Data Structure class. I was tasked with implementing a find & add method for the skiplist. Here is my program, I'm running into a segmentation fault when I add my second value into the skiplist. My first issue that I fixed was that I wasn't checking the first node in the list to see if it was nullptr, but that was not my only issue apparently. Add Method: void SkipList::add(const ElemType &el) { // Create a new node with the given element Node *newNode = new Node(el); // Get the height of the new node int newHeight = newNode->nodeHeight; // If the height of the new node is greater than the current list height, // update the list height. if (newHeight > listHeight) { listHeight = newHeight; } // Array to keep track of nodes to update Node *update[MAX_NUM_LISTS]; // Start from the top level Node *current = head[listHeight - 1]; // Initialize current correctly // If the list is empty, assign the first node to head if (head[0] == nullptr) { head[0] = newNode; } else { // Loop to traverse through list for (int i = listHeight - 1; i >= 0; i--) { // Move forward in the current level while (current->next[i] != nullptr && current->next[i]->elem < el) { current = current->next[i]; } // Store the node before which the new node should be inserted update[i] = current; } // Insert the new node at each level for (int i = 0; i < newHeight; i++) { newNode->next[i] = update[i]->next[i]; update[i]->next[i] = newNode; } } } Find Method: bool SkipList::find(const ElemType &el) const { // Start from the top level Node *current = head[listHeight - 1]; bool found = false; // Iterate through the levels of the skip list for (int i = listHeight - 1; i >= 0; i--) { // Move forward in the current level until reaching the end or finding a larger element while (current->next[i] != nullptr && current->next[i]->elem < el) { current = current->next[i]; } // Check if the current node's next node contains the target element if (current->next[i] != nullptr && current->next[i]->elem == el) { found = true; // Element found } } return found; // Element not found in the skip list } Main: int main() { ElemType inputs[] = {5, 7, 8, 10, 12, 17, 19, 22, 28, 31, 33, 35, 42, 51, 59}; SkipList list1; cout << "For list1 (same as in the slide 10 of Skip List1 Lecture Note):\n"; // for (int i=0; i(std::size(inputs)); i++) { cout << "add " << inputs[i] << endl; list1.add(inputs[i]); cout << "list1:\n" << list1 << endl; } if (list1.find(33)) cout << "33 is found!\n"; else cout << "33 is not found!!!!\n"; if (list1.find(70)) cout << "70 is found!\n"; else cout << "70 is not found!!!!\n"; if (list1.find(10)) cout << "10 is found!\n"; else cout << "10 is not found!!!!\n"; cout << "\n===================================\n"; cout << "For list2:\n"; ElemType inputs2[] = {19, 8, 17, 59, 12, 7, 5, 22, 28, 35, 33, 31, 42, 51, 10}; SkipList list2; for (int i = 0; i < static_cast(std::size(inputs2)); i++) { cout << "add " << inputs2[i] << endl.

When Jenkins saw the office, he laughed and said, "Well DeMur-or shall I say Maslick-I must say you have some admirers. As an American with African roots, you should have expected some lighthearted ribbing about your conversion to that strange religion of yours. Even you must admit that they do some weird things." Maalick replied, "No, I must suy that I did not expect this!" Jenkins recognized that Maalick was angry and upset ower the incident and promised to handle the situation. Over the next several months, Maalick received a series of notes left on his desk and car referencing black cats, black magic, requests for paim readings and notices about the disappearance of MarShawn DeMur. Not wanting to cause any problems or be labeled as a troublemaker, Maalick ignored these incidents, thinking that people would tire of the pranks and things would die down. However, on one occasion, he found on his desk several sheets of what appeared to be chants with a title at the top that read - Prayers for Black Folk:" Next to the pages was a book titled Myrical Practices from the Negro Experionce. Maalick immediately took the materials to the HR department and met with Ford. Ford told Maalick, "I have been out of the office a lot helping with the staffing of the new Northwestern facility and had no idea you were having these kinds of problems. Do you have any idea who is responsible for these actions?" "No I don't," said Maalick. "This is not the type of behavior that is condoned at Treton. Don't worry, I will handle this immediately. I am so sorry ahout all of this," said Ford. After Maalick left her office, Ford called a meeting of all department heads and informed them of the situation. Ford immediately sent an c-mail to all facility employees, reminding them of Treton's policies regarding discrimination and harassment and the penalties associated with such actions. By the end of the day, all department heads met with their employees with specitic wamings and orders for the behaviors to cease and desist. The days following were a bit tense in the office but calm. Maalick was relieved to not find any more notes or messages. Fond visited with Maalick on several oceasions to ensure that he was not continuing to experience any problems. Maalick was happy to report that, in his opinion, all was well. On Ford's last visit, Maalick took the opportunity to ask about two new systems manager openings. Promotion to a systems manager position would assist Maalick's career goals for advancenent with 'Treton. Fond sent Maalick the position description and encouraged him to apply. After reviewing the systems manager job requirements, Maalick believed that he had more than a good chance at a promotion. He spoke with Jenkins about the job duties and reyuirements and expressed his interest in the position. Maalick was informed that at that time, .

I have been tasked to write a code for a Singly Linked list that includes the following: Implement a singly linked list class with the following methods: - `void insertAtBeginning(int value)`: Inserts a new node with the given value at the beginning of the list. - `void insertAtEnd(int value)`: Inserts a new node with the given value at the end of the list. - `void deleteNode(int value)`: Deletes the first occurrence of a node with the given value. - `void display()`: Displays the elements of the linked list. I have everything EXCEPT for the deleteNode. I have it included, but it is throwing an error....I just need a little extra help to fix that part. My Code: # #include using namespace std; class Node { //user defined type. public: // public class modifier to access the class node. int value; Node* next; }; void display(Node *head) { if(head == NULL){ cout << "NULL" << endl; } else { cout << head->value << endl; display(head->next); } } void insertAtBeginning(Node**head, int newValue){ // Steps to add a Node to the beginning of the linked list //1.

I am trying to pass a date to a function in postgres. My function was working correctly. But then I had to introduce date as an input parameter.
