Write some code to evaluate the efficiency of the Java HuffmanTree class. a. The software will need to read a text and produce a character frequency table.After the table is built, a Huffman code tree is created, and the file's code becomes a sequence of '0' and '1' characters. c. Then, using that string as a model, produce and output the contents of the original file.
Given the binary search tree shown below. Draw what the tree would look like after deleting the value 7. Use one of the methods for deleting. Show your work. Thank you!
Using dev c++, I need to implement my own Binary Search Tree. There will be one number per line and you should incrementally insert them into your binary search. You should keep inserting numbers until you read a -1. Construct a binary search tree based on the numbers given on stdin. Then print out the pre-order, in-order, and post-order traversals each on their own lines. You should print out the numbers separated by spaces and it is acceptable to have a space at the end of each line. Sample Input 50 30 35 61 24 58 62 32 -1 Sample Output: 50 30 24 35 32 61 58 62 24 30 32 35 50 58 61 62 24 32 35 30 58 62 61 50
You are creating from scratch a binary search tree class with the methods insert, find, and delete in addition to the method getRandomNode(), which retrieves a random node from the tree. There should be an equal chance of selecting each node. Create a getRandomNode algorithm, put it into practise, and describe how you'd develop the other functions.
Describe a strategy for keeping a binary search tree as short as possible. One example might be to unload all of the values and to reinsert them in a particular order. How long does your approach take to add a value?
With a given binary search tree, you are asked to save the key of all the nodes into a file, then read the values one by one sequentially from the saved file and build a binary search tree that exactly replicates the original binary search tree. Describe how you would do it and give an example of 5 nodes.
Decode Binary String Assignment Using the Huffman tree depicted below, decode the following binary string. Use alternate colors to represent the individual letters and corresponding sub-string, separate sub-string by a blank space. You can do it by hand, scan, and upload. For example, 100010 1001 010 g o e 000001001110010100001000011101010001011100111010100011001111101111001
Create some code to see how well the Java HuffmanTree class performs. The programme will have to parse a text and generate a frequency table of characters from that document. Once the table is constructed, a Huffman code tree is made, and the file's code is represented by a string of '0' and '1' characters. Then, using that string as a template, re-generate the original file's contents, and print them.
A singly linked list contains n - 1 strings that are binary representations of numbers from the set {0, 1,.…, n – 1} where n is an exact power of 2. However, the string corresponding to one of the numbers is missing. For example, if n = 4, the list will contain any three strings from 00, 01,10 and 11. Note that the strings in the list may not appear in any specific order. Also note that the length of each string is lgn, hence the time to compare two strings in O(lgn). Write an algorithm that generates the missing string in O(n).

For the following questions, perform the operations in sequence. So, for example, part (b) should use part (a) as input. Follow the conventions regarding deletion and duplicate insertion used in class. Make a binary search tree by inserting the numbers 25, 14, 3, 2, 23, 75, 62, 52, 82, 79, 15, 100, 1, 18, 24, 8, 65, 5, 12, and 80 one at a time. You only need to show the final result, not each step. (a) Insert 55 into the tree. DInsert 14 into the tree.
