代做CSE 104程序、代写Data Structures程序、Java程序
CSE 104 – Data Structures & Algorithms
Department of Computer Science and Software Engineering, Xi’an Jiaotong-Liverpool University
CSE104 RESIT Coursework
Learning Outcomes
On successful completion of this assignment, students are expected to:
- understand and be able to apply a variety of data structures, together with their
internal representation and algorithms;
- be able to make informed choices between alternative ways of implementation,
justifying choices on grounds such as time and space complexity;
- be able to select, with justification, appropriate data structures to ensure efficient
implementation of an algorithm.
To Do: Design and code a Java program that:
1. Requests from the user for a text filename to read the text inside, then it counts the
frequency of each letter that file contains. There is no need to differentiate between upper and
lower cases while punctuation marks are ignored. For this assignment purpose, the text file
should be named as “Huff_in” with only letters inside. The program’s frequency table output
should be like this:
2. Based on the frequency table derived, a ternary Huffman codebook manager is
implemented in your program that produces as output a codebook (in tabular format) that
encodes letters based upon an input frequency table while the code generated should consume
minimum bandwidth using these for codes: {0, 1, 2}, e.g. symbol ‘e’ is encoded as ‘0’, ‘a’
as ‘12’, ‘c’ as ‘112’, etc.

3. Corresponding ternary Huffman encoder & decoder are also implemented that carry
out the encoding or decoding task based upon ternary codes received and a codebook as part
of input. The encoder encodes input letters based on the specified codebook. The decoder
will decode letters from ternary codes received using the codebook.
Coursework Submission
You should submit your Java program code files together with your report to the
entry I Provided on ICE. The submitted program solution should be well commented
together with another 4-page report with a file name “Report.pdf” or “Report.doc” (or
docx).
The report should not exceed 4 pages, without counting your .java files submitted
separately from this report) with the module title and your name/student number & signed

declaration For non-plagiarism shown on the title page. Your report should motivate &
explain your Data structure(s), what data structures/algorithms (rendered in pseudo code)
you have designed & why they are used, and how they are tested in your programs. You
should also analyse the space complexity (i.e. memory costs) of your data structures and the
time complexity of your algorithms developed (i.e. cost of running time asymptotically).
Marking
The mark distribution (100% total) is arranged as follows:
1. Correctness, efficiency, conciseness, & readability of your codes worth up to 75%:
Codebook manager 25%, encoder 25%, decoder 25%
2. Your report worth up to 25%.
This assignment: 100% of the RESIT marks.
