Expert Solution & Answer
Chapter 13, Problem 4RQ
Explanation of Solution
Traditional Systems Life Cycle:
- It is a highly structured process that has been in deployment since the 1950s.
- It is generally a 5 or 6 step process or stages that a project would go through.
- Also known as Systems Development Life Cycle (SDLC), is a very formal process with the below mentioned stages:
- System Analysis
System Design Programming - Testing of system
- Conversion/ Implementation
- Production a...
Explanation of Solution
Information Systems Prototyping:
- It is a radical approach than traditional systems but is only a working model that is developed in a test environment.
- It a repetitive, iterative approach and a hit or miss approach.
Advantages:
- When initial end user requirements are not clear, this method is the best approach.
- It is suitable for end-user interfaces.
- It can expedite the process while working with end users.
Disadvantages:
- There is high possibility for ignoring key steps in this process which is a dangerous flaw in getting the desired output on time...
Explanation of Solution
Application Software Package:
- It is a complete solution offered in a single package for a user, requiring minimum adjustments or requirements.
- The application providers cover product support for a period of time after delivery or through a setup of a maintenance contract.
Advantages:
- It is a quick and easy solution for generalised processes in an organisation.
- For example, basic features of accounting, human resources, and so on.
- A cost-effective approach to buy as a package rather than implementing a system from scratch...
Explanation of Solution
End-User Development:
- It provides user the ability to develop systems that require no or very less formal assistance from
information system technologies. - These days fourth generation language programs ensure for development of these packages.
Advantages:
- A solution for end user completely fulfilling its needs and requirements.
- They can be developed so it is easy to be applied in an existing workplace.
- These tools can provide an opportunity to improve programmer’s productivity.
Disadvantages:
- They are not suitable for heavy use or massive amounts of data...
Explanation of Solution
Outsourcing of Information systems development:
- Outsourcing is to allow a company with specialised knowledge and expertise to fulfil the user requirements.
- Cost is a big driver and company can utilise outsourcing when information system is not its core operations or in case its resources are limited.
Advantages:
- Company can save its resources as well as reduce costs by hiring external agencies rather than hiring additional manpower.
- It can depend on specialists to provide high quality solutions rather than developing systems in its own premises.
- Develop relationship and better experience...

Design a dynamic programming algorithm for the Longest Alternating Subsequence problem
described below:
Input: A sequence of n integers
Output: The length of the longest subsequence where the numbers alternate between being larger and
smaller than their predecessor
The algorithm must take O(n²) time. You must also write and explain the recurrence.
Example 1:
Input: [3, 5, 4, 1, 3, 6, 5, 7, 3, 4]
Output: 8 ([3, 5, 4, 6, 5, 7, 3, 4])
Example 2:
Input: [4,7,2,5,8, 3, 8, 0, 4, 7, 8]
Output: 8 ([4, 7, 2, 5, 3, 8, 0,4])
(Take your time with this for the subproblem for this one)
Design a dynamic programming algorithm for the Coin-change problem described below:
Input: An amount of money C and a set of n possible coin values with an unlimited supply of each
kind of coin.
Output: The smallest number of coins that add up to C exactly, or output that no such set exists.
The algorithm must take O(n C) time. You must also write and explain the recurrence.
Example 1:
Input: C24, Coin values = = [1, 5, 10, 25, 50]
Output: 6 (since 24 = 10+ 10+1+1 +1 + 1)
Example 2:
Input: C = 86, Coin values = [1, 5, 6, 23, 35, 46, 50]
Output: 2 (since 86 = 46+35+5)
Design a dynamic programming algorithm for the Longest Common Subsequence problem de-
scribed below
Input: Two strings x = x1x2 xm and y = Y1Y2... Yn
Output: The length of the longest subsequence that is common to both x and y.
.
The algorithm must take O(m n) time. You must also write and explain the recurrence.
(I want the largest k such that there are 1 ≤ i₁ < ... < ik ≤ m and 1 ≤ j₁ < ... < jk ≤ n such that
Xi₁ Xi2 Xik = Yj1Yj2 ··· Yjk)
Example 1:
Input: x = 'abcdefghijklmnopqrst' and y = 'ygrhnodsh ftw'
Output: 6 ('ghnost' is the longest common subsequence to both strings)
Example 2:
Input: x = 'ahshku' and y = ‘asu'
Output: 3 ('asu' is the longest common subsequence to both strings)

In other words, you will program the sine or cosine function yourself, without using any existing solution. You can enter the angles in degrees or radians. The program must work for any input, e.g. -4500° or +8649°. The function will have two arguments: float sinus(float radians, float epsilon); For your own implementation, use one of the following relations (you only need to program either sine or cosine, you don't need both): Tip 1: Of course, you cannot calculate the sum of an infinite series indefinitely. You can see (if not, look in the program) that the terms keep getting smaller, so there will definitely be a situation where adding another term will not change the result in any way (see problem 1.3 – machine epsilon). However, you can end the calculation even earlier – when the result changes by less than epsilon (a pre-specified, sufficiently small number, e.g.…arrow_forwardWrite a C program that counts the number of ones (set bits) in the binary representation of a given number.
