06. Assume that you have built a dense primary B+ tree index on a heap file containing 20,000 records. The key field for this B+ tree index is a 40 byte string and it is a candidate key. Pointers (i.e. record ids and page ids) are (at most) 10 byte values. The size of one disk page is 1,000 bytes . The index was built in a bottom-up fashion using the bulk-loading algorithm, and the nodes were filled up as much as possible. Then there are

Please Pleas Please Please help and create a simple python program that does the following.
write two functions: insertNode and forwardTraverse, for an XOR linkedlist, a.k.a, memory efficient doubly linked list (DLL) in C PL. Ordinary DLLs requires space for two addresses(one pointing to previous node and one to next node). However, XOR LLs use bitwise XOR operation tosave space for one address. Consider the below ordinary DLL.

Program in Java: topic: insertion sort The state and variable display: Unsorted Partition Reference Index: 7, Traversing Index: 1, Current Traversing Index Value: avocado, Condition Value Index: 0 Current Condition Value: apple, Swapping Condition: FalseCurrent Array: ['apple', 'avocado', 'orange', 'banana', 'strawberry', 'pineapple', 'plum', 'mango'] The Input must be:["apple", "avocado", "orange", "banana", "strawberry", "pineapple", "plum", "mango"]The assumptions and conditions: Sorted partition is on the right side.The order is increasing alphabetically but the strings that has an odd length should be the first to be sorted then the strings with the even length goes next The result or Output must be:['apple', 'avocado', 'mango', 'pineapple', 'banana', 'orange', 'plum', 'strawberry']

in C++ solve the following question in the picture :
you need to design, analyze, and implement algorithms to read in a sequence of characters from standard input and maintain the characters in a linked list with no duplicates. When you read in a previously unseen character, insert it at the front of the list. When you read in a duplicate character, delete it from the list and reinsert it at the beginning. The program implements the well-known move-to-front strategy which is useful for caching, data compression, and many other applications where items that have been recently accessed are more likely to be re-accessed. Requirements: The program should read a sequence of characters. The program should insert unseen character at the front of the list. The program should check if the character is not in the list to be inserted at the front of the list. The program should delete a duplicate character and delete it from the list and insert it at the beginning of the list. The program should check if the character is already in the list and…
3. both "selcted answers" are wrong and obviously question 18 is true i just need an explanation on that one. Question 19 is just between the 3 answer choices and an explanation on that on would be great too please.
• Description o Please simulate a Best Fit memory block allocation algorithm. • Your program runs without command line arguments. For example, your program may run like "./P5.exe". • At the beginning, we have a linked list of 1024 nodes, each contains a free memory block of 1024 Bytes. The linked list node should contains both block id and free memory size. For Best Fit policy, your linked list needs to be sorted in the ascending order of the memory block size. Your program starts by reading a list of memory requests from a file named "requests.txt", which consists of a list with two types of requests: • A: Allocation of a memory region of a particular size. For example, "A 1 512" specifies a request with id of 1 for an allocation of 512 Bytes memory block. Request Id starts from 1 and increases incrementally. o R: Release of the memory requests by a particular request id. For example, "R 1" releases the memory allocated back to the identified memory block. • When processing each…
