Chapter 5, Problem 6RQ
Program Plan Intro
SQL:
- SQL stands for “Structured Query Language”.
- The current version of SQL is “ANSI SQL – 92”.
- SQL is not a
programming language. It is text-based and it is also called as data sublanguage.- In order to get SQL as a complete programming language, it should be included in scripting languages like Java, C#, and so on.
- It contains constructs which are used to define and process
database . They are executed using DBMS-supplied command prompt. - Some of the DBMS products provide GUI tools in order to perform tasks are as follows:
- SQL Server
- Oracle Database
- MySQL
Join: Join is a relational operation, which combines the data from two or more tables into single table or view, then that is called as Join.

Design a dynamic programming algorithm for the problem described below
Input: A list of numbers A = = [a1,..., an].
Output: A contiguous subsequence of numbers with the maximum sum.
The algorithm must take O(n) time. You must also write and explain the recurrence.
(I am looking for an i ≥ 1 and k ≥ 0 such that a + ai+1 + ···ai+k has the largest possible sum among all
possible values for i and k.)
Example 1:
Input: A[5, 15, -30, 10, -5, 40, 10].
Output: [10, 5, 40, 10]
Example 2:
Input: A = [7, 5, 7, 4, -20, 6, 9, 3, -4, -8, 4]
Output: [6,9,3]
Design a dynamic programming algorithm for the Longest Increasing Subsequence problem
described below:
Input: A sequence of n integers
Output: The length of the longest increasing subsequence among these integers.
The algorithm must take O(n²) time. You must also write and explain the recurrence.
Example 1:
Input: [5, 3, 6, 8, 4, 6, 2, 7, 9, 5]
Output: 5 ([3, 4, 6, 7, 9])
Example 2:
Input: [12, 42, 66, 73, 234, 7, 543, 16]
Output: 6 ([42, 66, 73, 234, 543])
Design a dynamic programming algorithm for the Subset Sum problem described below:
Input: A set of n integers A and an integer s
Output: A subset of A whose numbers add up to s, or that no such set exists.
The algorithm must take O(n·s) time. You must also write and explain the recurrence.
Example 1:
Input: A = {4, 7, 5, 2, 3}, s = 12
Output: {7,2,3}
Example 2:
Input: A{4, 7, 5,3}, s = 6
Output: 'no such subset'

Project Requirements The project consists in designing and implementing a Web application according to the methodology and the technologies illustrated and developed during the course.

The application must be realized with a combination of the following technologies: PHP MySQL HTML/CSS JavaScript, jQuery, etc templating The requirements are 2. Project size The application must have at least 18 SQL tables The number of SQL tables refers to the overall number of tables (including relation normalizations). 3. Methodology The application must be realized by adopting separation of logics, session management, and generic user management (authentication/permissions). Missing one of the above might correspond to a non sufficient score for the project.

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.

To get full points, you must be able to explain to the instructor the individual parts of the IntelHex line (see below), as well as any part of your code. Definition:The checksum is calculated as the two's complement of the sum of the individual bytes from the beginning of the line to the checksum. Example:If you enter this string: :10010000214601360121470136007EFE09D21901XX You should get a checksum of 40 instead of XX. Demonstrate the completion of the task by calculating checksums, for example, for the following strings: :100010000C9445000C9445000C9445000C944500xx:100020000C9445000C9445000C9445000C944500xx:100030000C9445000C9445000C9445000C944500xx:100040000C9445000C9445000C9445000C944500xxarrow_forward
