- When an author produces an index for his or her book, the first step in this process is to decide which words should go into the index; the second is to produce a list of the pages where each word occurs. Instead of trying to choose words out of our heads, we decided to let the computer produce a list of all the unique words used in the manuscript and their frequency of occurrence. We could then go over the list and choose which words to put into the index. The main object in this problem is a "word" with associated frequency. The tentative definition of "word" here is a string of alphanumeric characters between markers where markers are white space and all punctuation marks; anything non-alphanumeric stops the reading. If we skip all un-allowed characters before getting the string, we should have exactly what we want. Ignoring words of fewer than three letters will remove from consideration such as "a", "is", "to", "do", and "by" that do not belong in an index. In this project, you…When an author produces an index for his or her book, the first step in this process is to decide which words should go into the index; the second is to produce a list of the pages where each word occurs.

The constructor's maximum size should be preallocated to the arrays. Compare your program's effectiveness to that of a typical implementation.
- Hi ! Im having trouble with splitting the data to meet the conditions and then converting to a list and would love some help to solve this! This is the question. The datatype of the array created by NumPy in Task 1 is unstructured. This is because, in the default setting, NumPy decides the datatype for each value. Also, the output in Task 1 contains the header row that may not be required in our assignment. So, remove the header row and convert all the columns to type float (i.e., "float") apart from the columns specified by the input parameter indexes (mentioned below). Also, the remaining columns which are not mentioned in indexes should be in Unicode of length 30 characters (i.e., "<U30"). Finally, every row is converted as a type tuple (e.g., tuple(i) for i in data). I need to produce a function data_type_format(data, indexes) that can complete the above-mentioned task, where, the input data is a NumPy array and indexes contains the column indices (in list) which are to be…Enlist the cursor types.Create a BST implementation that uses three arrays to represent the BST: one with keys, one with array indices for left links, and one with array indices for right links. The arrays should be preallocated to the maximum size specified in the constructor. Compare your program's performance against that of the usual implementation.
- The following are the operations that you can do using a single linked list. Choose only one operation then create the algorithm and simulate. The attached Rubric will be used in evaluating the activity. 1. Delete a particular node in a single linked list 2. Delete the first node of a single linked list 3. Insertion after a given node of a single linked list 4. Insertion at a given position in a single linked list 5. Insertion before a given node in a single linked list 6. Reverse a single linked list EX: Delete the last node of a single linked list Problem" Deletion of the last node in a single linked list Algorithm" Step 1: if HEAD = NULL Write UNDERFLOW Go to Step 8 Step 2: SET PTR = HEAD Step 3: Repeat Steps 4 and while PTR à NEXT = NULL Step 4: SET PREPPTR = PTR Step 5: SET PTR =PTR à NEXT [End of loop] Step 6: SET PREPTR à NEXT = NULL Step 7: FREE PTR Step 8: EXIT…Given a nested list named table, use nested loops to print each element in the nested list. Each element should be on its own line. The elements in the first position of each sublist should be print first, (in the order of the sublists) followed by the elements in the second position, etc ..... You may assume that every sublist has the same number of elements. Hint: Iterate over your nested list by indexes rather than by elements. this is for pythonWrite a python code for #3
- You are working for GreatDataStructures Inc. You have to pick a data structure for a problem that requires accessing all the stored elements quickly as well as adding elements to and removing elements from the end of the list of elements. The number of elements in the list is not known. The best data structure to choose is a linked list with no tail reference a linked list with a tail reference a doubly-linked list an array list O an array stackHow does a link-based implementation of the List differ from an array-based implementation? Select one: a. All of these b. A link-based implementation does not need to shift entries over to make room when adding a new entry to the List c. A link-based implementation is sized dynamically so it takes up only the memory to hold the current entries d. A link-based implementation does not need to shift entries up to remove a gap when removing an entry from the ListPlease answer in Java, thank you. The purpose of this assignment is to practice your knowledge of how a linked data structure is implemented. This is a more advanced version of a linked list, and will help to give you practice in how to deal with data structures connected through references. This assignment is very important to help you understand the fundamentals of Linked Lists. At the end of this assignment, you should be able to fully understand how any variation of a Linked List is implemented. Instructions: For this project you will be implementing a new data structure called LinkedGrid. This is a linked type data structure version of a 2D array. The LinkedGrid can support any combination of dimensions (n x n, n x m, or m x n, where n > m) This data structure has a singly linked system which allows you to traverse the grid in multiple directions in addition to allowing you to retrieve specific rows and columns. The following diagram gives a rough visual of this data…
