Given head which is a reference node to a singly-linked list. The value of each node in the linked list is either 0or 1. The linked list holds the binary representation of a number. Return the decimal value of the number in the linked list.

Lists and tuples are two distinct data structures.

C PROGRAMMING Implement dijkstras alorithm  Check that the Graph graph, and starting node, id, are valid• Create the set S containing all the networks (vertices) except the source node (you might wantto use an array for this.• Create an array to represent the table D and initialise it with the weights of the edges from thesource node, or infinity if no edge exists. You should use the constant DBL_MAX to representinfinity.• Create an array to represent the table R and initialise it with the next hops if an edge existsfrom the source, or 0 otherwise.• Then repeatedly follow the remaining rules of Dijkstra’s algorithm, updating the values in D andR until S is empty.• Each of the values required to complete the above can be found by calling the variousfunctions (get_vertices(), get_edge(), edge_destination(), edge_weight(), etc.)in the supplied graph library.• Once Dijkstra’s algorithm has run, you will need to create the routing table to be returned byallocating enough memory for the…

With the concepts of Queue Data Structure, write the functions performing the following tasks: 1. Insertion of an element in the Queue i.e. enqueue() 2. Deletion of an Element from the Queue i.e. dequeue() 3. Display All Elements in the Queue i.e. dispqueue() 4. Display the Element at the Front i.e. dispfront() 5. enqueue() the Queue with the elements in ascending order. After that, use the above four functions to display the same elements in the Queue in descending order.

Java Design and draw a method called check() to check if characters in a  linked list is a palindrome or not e.g "mom" or "radar" or "racecar. spaces are ignored, we can call the spaces the “separator”. The method should receive the separator as a variable which should be equal to “null” when no separator is used.

Write a program in Java to manipulate a Double Linked List:   Count the number of nodes Insert a new node before the value 7 of Double Linked List Search an existing element in a Double linked list (the element of search is given by the user) Suppose List contained the following Test Data: Input the number of nodes : 4Input data for node 1 : 5Input data for node 2 : 6 Input data for node 3 : 7 Input data for node 4: 9

Don't give me AI generated answer or plagiarised answer. If I see these things I'll give you multiple downvotes and will report immediately.
