• 课程名称：University of New South Wales COMP9021 PRINCIPLES OF PROGRAMMING
• 完成周期：2天

描述

1.1. Aim. The purpose of the assignment is to:
• develop your problem solving skills;
• design and implement a solution to a problem in the form of medium sized Python program;
• in particular but no to only, parse text in files, make use of the dynamic programming algorithmic technique, implement class methods.

1.2. Submission. Your programs will be stored in a file named diff.py. After you have developed and tested your program, upload it using Ed (unless you worked directly in Ed). Assignments can be submitted more than once; the last version is marked. Your assignment is due by April 24, 10:00am.

1.3. Assessment. The assignment is worth 13 marks, distributed as indicated in Part 3. It is going to be tested against a number of inputs. For each test, the automarking script will let your program run for 30 seconds. The outputs of your programs should be exactly as indicated.

1.4. Reminder on plagiarism policy. You are permitted, indeed encouraged, to discuss ways to solve the assignment with other people. Such discussions must be in terms of algorithms, not code. But you must implement the solution on your own. Submissions are routinely scanned for similarities that occur when students copy and modify other people’s work, or work very closely together on a single implementation. Severe penalties apply.
