Q1:Need to do the complete coding in python This is the starting codeSee Answer
Q2:A Palindrome is a word that is the same when written forwards and when written backwards. For example, the word "refer" is a Palindrome. The Dafny program ex3errors.dfy, which you will find on the website, contains a method PalVerify that is supposed to verify whether a word is a Palindrome, where the word is represented as an array of characters. The method was written by a novice software engineer, and contains many errors. i Without changing the signature or the code in the while loop, fix the method so that it veriifes the code. Do not add any Dafny predicates or functions: keep the changes to a minimum. ii Write a tester method (you may call it anything you like) that verifies that the testcases refer, z and the empty string are Palindromes, and ry and 123421 are not. The tester should not generate any output. See Answer

Q16:This Competency Assessment assesses the following outcome(s): IT232M1: Explore various software process models. GEL-8.03: Apply critical thinking to formulate a logical solution to a problem. Software Design and Modeling Purpose Given a requirement, you will examine various software design and modeling techniques by diagramming and analyzing a solution. You will create an IPO chart, pseudo-code, flowchart diagram and perform a desk-check analysis to help formulate your solution to the problem posed. Assessment Instructions Note: For this assessment, you will not be writing any actual code. You are just going through the design and modeling of this scenario. Using an IPO chart, a flowchart diagram, and pseudocode, you will design a routine that will accept a Fahrenheit temperature and convert that temperature to its Celsius and Kelvin equivalents. Hint. The term routine can mean function, subroutine, procedure, etc., depending on the language in question. Assessment Requirements A user enters in a Fahrenheit temperature, and gets back two values: Celsius temperature Kelvin temperature The code routine will accept one argument, tempFahrenheit and will calculate two values, tempCelsius and tempKelvin. It will call two routines internally: • ConvertFahrenheitToCelsius will be a routine to convert a Fahrenheit temperature to Celsius • ConvertFahrenheit ToKelvin will be a routine to convert a Fahrenheit temperature to Kelvin. Use these variable and routine names in your solution. Research and find the formulas to convert Fahrenheit temperature to Celsius and Kelvin and then apply critical thinking skills to formulate a logical programmatic solution to convert the user-entered value of Fahrenheit temperature to Celsius and Kelvin equivalents.See Answer
Q17:Then design the two routines that will implement the formulas you found in your research. We do this by examining how the routines should behave and walk ourselves through the design using the following tools. 1. Create your IPO chart. This is where you determine your inputs-processes- outputs. 2. Create a flowchart diagram showing the flow of logic for the solution to these problems. 3. Create your pseudo-code. Hint: Pseudocode is a mix of simple syntax from real programming languages and English. When modeling your full routine or program you will show every aspect of it in the pseudocode. In the case of adding your algorithms or processing to IPO charts or flowcharts, you can use snippets of the pseudocode to only show the pertinent processing. How can you prove that your algorithm is correct? You will perform an experiment and then analyze your results to determine if your algorithm is correct. We must follow the scientific method to ensure repeatable results in our experiment. First, we determine a hypothesis: "What value is computed for an input of 3"? We note the expected result from our hypothesis. It will later be compared to the actual results from our experiment to determine if the experiment passed or failed. The process we use to perform our experiment is called a desk check. A desk check is when you identify all the variables used in the routine and place them in a table. You then examine a potential input value, step through the code, and fill out the table at each step in the code. So, when a variable in your code has its value changed, be sure to update that new value in your desk checking table. At the end of the table you will have calculated your actual result. This investigation will identify if you have designed the correct logic to realize a correct result. The actual result should match the expected result. You must desk check each routine at least three times. After you have completed your experiment, you need to analyze your results. Did you prove or disprove your hypothesis?See Answer
Q18:Discuss the results of your experiment in a Word document. Show your analysis and your data then explain your conclusions. EXAMPLE: Here is an example scenario using the square algorithm. The square routine will take a number in as a parameter, perform calculations to determine the square of the number and return the result. You will examine the routine and determine the variables of interest. Then experiment with different input values as you build your desk check tables. Sample Desk Check: Using your pseudo-code algorithm. This routine has three variables of interest: num-the input parameter • i-the value of the counter Value - the result of the calculation Our hypothesis will be: If you call the square routine with an input number, the calculated result returned by the square routine will be that number squared. The input value times itself (number X number). 1. Hypothesis: If you call the square routine with an input of 3, the calculated result should be 9. Experiment Desk check using 3 as input parameter Expected Result: square(3) = 9 2. num, value 033 136 239 Actual Result 2 3. Hypothesis: If you call the square routine with an input of 7, the calculated result should be 49.See Answer
Q19:4. Experiment Desk check using 7 as input parameter Expected Result square(7) = 49 i numvalue 077 17 14 27 21 37 28 47 35 5 7 42 6 7 49 Actual Result 49 Directions for Submitting Your Assessment Submit one document that contains your IPO chart, flowchart, pseudocode and analysis, and conclusions. Name your assessment document according to this convention: The file should be saved as: IT232_YourLastName_M1. Submit your completed assessment to the Dropbox. Review the checklist rubric before beginning this activity.See Answer
Q20:For this project, you can form a group and the maximum number of members in one group is 2. You should find your teammate by yourself. You can also work on it individually. In this project, you will implement Spectrum-Based Fault Localization (SBFL) for real-world Java programs with unit tests. Specifically, you will calculate suspiciousness values of source code elements by using the 4 formulae in Page 9 of Module 6 slides. The program you will analyze is JFreeChart (https://github.com/jfree/ifreechart) and you don't need to collect its coverage information. Instead, the coverage data has been provided in D2L. You just need to write your own program by using any programming language (e.g., Java, Python, C++, etc.) to process the coverage data and calculate the suspiciousness values based on the 4 SBFL formulae. Explanation of the coverage data: 1. The coverage data (CoverageData.tar) is in the module "Course Project" in D2L as follows. Course Project - Add dates and restrictions... Print Settings/n1. The coverage data (CoverageData.tar) is in the module "Course Project" in D2L as follows. Course Project. Add dates and restrictions... Add a description... Upload / Create Project Instructions PDF document CoverageData.tar GZ File Existing Activities ✓ Bulk Edit Print A+ Settings 2. You need to uncompress the .tar file firstly and then you will find multiple .gz files. For each .gz file, you will find that the first line represents one test case and other lines represent the source code methods covered by this test. The example is as follows, and “true” just represents that the test case is a passed test. Please note that the tests and source code methods are represented by Java bytecode. You can learn Java bytecode by yourself if you are interested (https://www.irebel.com/blog/java- bytecode-tutorial). However, it is not required for this project. You just need to view them as unique tests and source code elements (source code methods)./nTest case org.jfree.chart. annotations.TextAnnotationTest.testEquals true org/jfree/chart/event/ChartChangeEvent:<init>:(Ljava/lang/Object;}V org/jfree/chart/event/ChartChange Event:<init>: (Ljava/lang/Object; Lorg/jfree/chart/JFreeChart; Lorg/jfree/chart/event/ChartChange Event Type;) org/jfree/chart/annotations/TextAnnotation:<init>:(Ljava/lang/String;)V org/jfree/chart/annotations/TextAnnotation:getText: ()Ljava/lang/String; org/jfree/chart/annotations/TextAnnotation: setText: (Ljava/lang/String; )V org/jfree/chart/annotations/TextAnnotation:getFont: () Ljava/awt/Font; org/jfree/chart/annotations/TextAnnotation: setFont: (Ljava/awt/Font; )V org/jfree/chart/annotations/TextAnnotation:getPaint: ()Ljava/awt/Paint; org/jfree/chart/annotations/TextAnnotation:setPaint: (Ljava/awt/Paint; )V org/jfree/chart/annotations/TextAnnotation:getTextAnchor: ()Lorg/jfree/ui/TextAnchor; org/jfree/chart/annotations/TextAnnotation: setTextAnchor: (Lorg/jfree/ui/TextAnchor;)V org/jfree/chart/annotations/TextAnnotation:getRotationAnchor:()Lorg/jfree/ui/TextAnchor; org/jfree/chart/annotations/TextAnnotation:setRotationAnchor: (Lorg/jfree/ui/TextAnchor;)V org/jfree/chart/annotations/TextAnnotation:getRotationAngle: ()D org/jfree/chart/annotations/TextAnnotation: setRotationAngle: (D)V Source code method 3. You should write code to read all .gz files and convert the data required for SBFL. 4. There are no failed tests in the data. But you should manually set some tests as failed tests. Final Submission 1. Your code to process coverage data and to implement the 4 SBFL formulae in Page 9 of Module 6 slides. Please note that you should also provide one command to execute your program. The input of your program should be the coverage data and the output should be the ranking list of source code methods with the suspiciousness values. 2. The final list of source code methods with the suspiciousness values 3. One-page report to describe how you complete this project.See Answer
