Problem Description: The student shall turn in five functions. You should use mymap1 and mymap2 in problem 3, 4, and 5 if it is needed. However, the best way to do so is you use built-in map to finish problem 3, 4, and 5 first. After they work, replace map with mymap1 or mymap2. If they still work, you can say that you implement them all correctly. If it doesn’t work, then you now that your mymap1 or mymap2 maybe incorrect. Functions to work out: 1. Define a function mymap1 with the same type and behavior as built-in map function but without using map. This should be one-line of code. Use foldr or foldl) (refer to problem Exercise 24 on page 147) 2. Define a function mymap2 with the same type and behavior as map. No map, foldr, or foldl can be used. (refer to problem Exercise 26 on page 147) 3. Write a function ordlist of type char list -> int list that take a list of characters and returns the list of integer codes of those characters. For example, if you evaluate ordlist [#”A”, #”b”, #”C”] you should get [65, 98, 67] (refer to Exercise 2 on page 144) 4. Write a function mylength fo type ‘a list -> int that returns the length of a list. You cannot use the built-in length function. (refer to Exercise 11 on page 145) 5. Write a function max of type int list -> int that returns the largest element of a list of integers. Your function need not behave well if the list is empty.

InstructionsIn this final assignment, you will develop a paper that reviews some of the main topics covered in the course. Compose an essay to address the elements listed below.Identify the components of an information system (IS) using the five-component framework, and provide a brief summary of each.Explain Porter’s five forces model.Management IS (MIS) incorporate software and hardware technologies to provide useful information for decision-making. Explain each of the following IS, and use at least one example in each to support your discussion: a collaboration information system, a database management system, a content management system, a knowledge management/expert system, a customer relationship management system, an enterprise resource planning system, a social media IS, a business intelligence/decision support system, and an enterprise IS.Identify and discuss one technical and one human safeguard to protect against IS security threats.There are several processes that can be used to develop IS and applications such as systems development life cycle (SDLC) and scrum (agile development). Provide a brief description of SDLC and scrum, and then discuss at least one similarity and one difference between SDLC and scrumSum up your paper by discussing the importance of MIS.Your paper must be at least three pages in length (not counting the title and reference pages), and you must use at least two resources. Be sure to cite all sources used in APA format, and format your essay in APA style.
