- IN C LANGUAGE When inserting a node into a linked list, where (in memory) will that node be placed if there is no overflow? A) The location of the AVAIL pointer B) The next contiguous spot of memory from the last node C) The very end of the contiguous memory block D) A randomized memory location4. Consider the following linked list: first 10 12 14 16 18 struct NodeType { int val: NodeType* link; } NodeType* first; Write a traversal loop that sums the values of the linked list structure member yal starting at the beginning of the list to the end and outputs (cout) the sum (you only have to write the cout statement, not the actual sum). Define any additional variables needed. Ensure the beginning of the list is preserved in NodeType* first. You do not need to write any #include, using or main statements.READ THE PROBLEM AND USE PYTHON PROGRAMMING LANGUAGE!!In this problem, you are going to implement a filesystem using a tree data structure. Similar to a filesystem, each node (or file), may have multiple children. If the specified path does not exist, then you should disregard that file. Once you are done adding elements to the filesystem, you should print the directory structure in the specified format. Required modifications: 1. Insertion of a new element 2. Printing of the directory from the root node. 3. Parsing of the input. Input Format First line is the name of the root directory. Second line, n, is the number of subdirectories that follows. For each line that follows, it shows the following format: Filename-root node,next path,next path,... Constraints You may assume that the filenames are all alphabetical characters with no special characters. n < 100 The maximum path length is 20 (including the root directory). You may assume that there are no similar…
- Use C++ Programming Language. Objective Define a circular buffer data structure and test it. Problem Description: A circular buffer (also called a circular queue) is circular list of nodes where data items are added on one end of the buffer and removed from the other end. Because the nodes form a circular list, the list has no end or beginning: the tail node points to the head node, creating a ring of nodes. You may think of the nodes as containers or slots that are all initially empty but can be assigned a value in their data field info. Every time a new data item is inserted (inserting to a buffer is often referred as Writing), one slot is filled and the buffer has one less empty slot. Every time a data item is removed (referred to as Reading), the buffer has one more empty slot. Since the list has no beginning and no end, a pointer (writeIndex) is used to mark the next empty slot to write to and a second pointer (readIndex) is used to mark the next node to read from. The…A B+-tree is to be stored on disk whose block size is 2048 bytes. to be stored are 64 bytes, and their key is 24 bytes. The data records Determine the values for M and L for the B+-tree. Assume pointers are 4 bytes each. oints For the problem above, in the worst case, how many levels are needed to store 16,000,000 records?Hashing 1. Develop an algorithm to demonstrate hashing using hash table with modulo as the hash function. Assume the size of the hash table as 10. To avoid collisions in case of identical keys for two different elements, use Linear Probing collision resolution technique. 2. Analyse time and space complexity of the designed algorithm 3. Write C++ program to implement Hashing 4. Test and debug the program 5. Obtain the results 6. Document the report

You need to be able to find the first item in O(1) time, add to the end in O(1), and remove items in O(1) time, given some id (not index), from anywhere in the line. Additionally, you need to be able to find an item in line in O(1) time and see what items are near it (in front of or in back of) in O(1), possibly more (each is O(1) time).
