- Describe the two typical components of a single linked list node.arrow_forwarddef pq strip_key(source, kev): III Removes all values from source that have a priority less than key. Use: pq_strip_key (source, key) Parameters: source - a priority queue (Priority_Queue) key a key value (?) Returns: None #your code here returnarrow_forwardunique 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_forward
- In linked list implementation of a queue, which of the following pointers will change during an insertion into a NONEMPTY queuearrow_forwardWhat is Synchronized queue? explai with pseudo code.arrow_forwardQuestion 15 Why does our node class have two versions of the link member function? One is public, the other is private. One is to use with a const pointer, the other with a regular pointer. One returns the forward link, the other returns the backward link. One returns the data, the other returns a pointer to the next node.arrow_forward
- Establish a linked queue, and run operations in the linked queue. General operations include：Create queue, one element enqueue, one element dequeue, check if the queue is full.
