Write a C++ program to create Huffman codes. Program input is a file called freq.txt (make up your own file for testing) that contains data on the characters in some cleartext file in the form of each character's non-zero frequency of occurrence in the cleartextfile. (Note that these are frequency counts, not percentages, and it doesn't matter if the values do not sum to 100.) You can assume that freq.txt contains only characters from the standard ASCII 128 character set and that the results are ordered by the ASCII integer for each character. The end-of-line character in a text file is a non-printable line feed character, with ASCII code 10, and will be written in the freq.txtfile as LF. Thus the freq.txt file might look like
LF 2
c 3
d 5
e 14
f 2
Your program should create a "code table" that gives each character and its binary Huffman code. Save this information in an external file called codetable.txt where each line of the file is a character and its code, ordered by the ASCII value of the character.
How many page faults would happen for the given replacement algorithms, assuming one, two, three, and four frames?
Individual project for this course is in form of Service Request from Huffman Trucking. It is essential for student to access Service Request: SR-ht-001. Design a Benefits Election System.
Write efficient backtracking algorithm which inputs the integer N, and outputs all of the ways which a group of ascending positive numbers can be summed to N.
Today ISDN cost $40 every month for BRI service which includes 1 D Channel and 2 B Channels. Every channel is capable of transmitting 64kbps of voice, data, video or fax for a total of 128 kbps.
Prepare two arrays of integers, each holding 10-elements of data. Make a third array of integers for a result array. The main program will take the 2-arrays of integers and pass them to the function subtract().
Suppose the cost of seek is 5milliseconds, while the disk transfer rate is 40 mgbytes per second. Find the cost of sorting the relation , in seconds, w/bb = 1 & w/ bb= 100.
A group of ten people require to decide which one flavor of ice cream they will all order, out of three options. The algorithm can question and re-question participants.
Find out number of phases needed, and estimate cost of Multi Phase Multiway Merge Sort. Write all BCNF violations. Decompose relations, as essential, into collections of relations whic hare in BCNF.
A group of N stations share a 56-kbps pure ALOHA channel. Every station outputs a 1000-bit frame on an average of once every one-hundred secs, even if the previous one has not yet been sent.
Data Structures and Algorithm Design
As queries are expensive, you would like to calculate median using as few queries as possible. Provide the algorithm which finds median value using at most O(log n) queries.
