Your code should contain a PHP function that, accepting the string of 1000 numbers in input, is able to:

1) Find the 5 adjacent numbers that multiplied together give the largest product.

2) Given the product from above, computes the sum of the factorial of each term of such product

Example, if the product is 5046, computes 5! + 0! + 4! + 6!

NOTE:

• If the file doesn't contain 1000 numbers or contains some characters in between, it should be discarded and the application should inform the user that the file is not format correctly.
• Add a tester function to check the behavior of your PHP function.
• Follow the guidelines discussed and showed in class to avoid losing points.

How would you reply to this discussion:

Cloud Computing is a way to store massive amounts of information on remote servers. Unlike saving information on your local hard drive or flash drive, cloud storage is almost like a magical place that keeps (so we hope) your information safe and secure. A couple of different cloud computing examples are.

1. Communication: these would be examples of Skype or WhatsApp. I have used both applications, though I haven't used skype in many years, I currently use WhatsApp daily,

2. Backup and Recovery: Large storage to save your information. I always like to say, It's somewhere in the cloud. Examples, Dropbox, Google Drive, and Amazon S3. Out of these three, I have only used Dropbox, this was used during my Web Design class.

3. Social Networking: We all know about social networking, we all may use them on a daily basis. Also, social networking is the most popular of cloud computing. Some examples are Facebook, LinkedIn and Instagram to name a few.

This week I actually learn a lot. Back in my computer help desk days, I remember building a computer by imaging. But it was different to see the different way to divide the disk space. Very interesting.

1. Software Decode: Write a function that accepts an in-order array of unsigned integer values. The function shall then scan the array for a specific pattern: Three values contained within the array equally spaced 20 units apart. The function shall return the index position within the original array where the pattern begins or -1 if not present.

   Given the input array: data[] = {10,20,31,40,55,60,65525} The function shall return: 1

1. The function removeAt of the class arrayListType removes an element from the list by shifting the elements ofthe list. However, if the element to be removed is at the beginning ofthe list and the list is fairly large, it could take a lot ofcomputer time. Because the list elements are in no particular order, you could simply remove the element by swapping the last element ofthe list with the item to be removed and reducing the length of the list. Rewrite the definition of the function removeAt using this technique.
2. The function remove of the class arrayListType removes only the first occurrence of an element. Add the function removeAll to the class arrayListType that would remove all occurrences of a given element. Also, write the definition ofthe function removeAll and a program to test this function.

Due 9/27

Please submit SQL statements as a plain text file (.txt). If blackboard rejects txt file you can submit a zipped file containing the text file. Word, PDF, or Image format are not accepted. You do not need to show screen shot. Make sure you have tested your SQL statements in Oracle 11g.

Problem 1. Please create the following tables for a tool rental database with appropriate primary keys & foreign keys. [30 points]

Assumptions:

1. Each tool belongs to a category.
2. Each category may have a parent category but the parent category should not have parent category (so at most two levels). E.g., a Tool A belongs to electric mower, and electric mower belongs to mower. Mower has no parent category.
3. Each tool can be rented at different time units. The typical time units are hourly, daily, and weekly. There is a different price for each time unit and tool combination. E.g., tool A may be rented at $5 per hour, $30 per day, and $120 per week.
4. Each customer can rent a tool for a certain number of time units. If the tool is returned late a late fee will be charged.

The list of tables is:

Tables:

Cust Table:

cid, -- customer id

cname, --- customer name

cphone, --- customer phone

cemail, --- customer email

Category table:

ctid, --- category id

ctname, --- category name

parent, --- parent category id since category has a hierarchy structure, power washers, electric power washers, gas power washers. You can assume that there are only two levels.

Tool:

tid, --- tool id

tname, --- tool name

ctid, --- category id, the bottom level.

quantity, --- number of this tools

Time_unit table allowed renting unit

tuid, --- time unit id

len, --- length of period, can be 1 hour, 1 day, etc.

min_len, --- minimal #of time unit, e.g., hourly rental but minimal 4 hours.

Tool_Price:

tid, --- tool id

tuid, --- time unit id

price, -- price per period

Rental:

rid, --- rental id

cid, --- customer id

tid, --- tool id

tuid, --- time unit id

num_unit, --- number of time unit of rental, e.g., if num_unit = 5 and unit is hourly, it means 5 hours.

start_time, -- rental start time

end_time, --- suppose rental end_time

return_time, --- time to return the tool

credit_card, --- credit card number

total, --- total charge

Problem 2. Insert at least three rows of data to each table. Make sure you keep the primary key and foreign key constraints. [20 points]

Problem 3. Please write ONE SQL statement for each of the following tasks using tables created in Problem 1. You can ONLY use conditions listed in the task description. Task 1 and 2 each has 5 points. Tasks 3 to 6 each has 10 points. [50 points]

Task 1: return IDs of rentals started in August 2019.

Hint: function trunc(x) converts x which is of timestamp type into date type.

Task 2: Return names and quantity of all tools under the category carpet cleaner. You can assume there is no subcategory under carpet cleaner

Task 3: return number of rentals per customer along with customer ID in the year 2019 (i.e., the start_time of the rental is in 2019).

Task 4: return IDs of tools that has been rented at least twice in 2019.

Task 5: return the price of renting a small carpet cleaner (the name of the tool) for 5 hours.

Hint: find unit price for hourly rental and then multiply that by 5.

Task 6: return names of customers who have rented at least twice in year 2019 (i.e., rental’s start time is in 2019).

implement the reverse() method that changes the ordering of the items within a doublylinkedlist class. don't return anything and make sure it executes without errors on lists with no items or one item

example:

fruits = DoublyLinkedList()
fruits.append('apple')
fruits.append('banana')
fruits.append('cherry')
for i in fruits:
    print(i)
>> apple
>> banana
>> Charlie

fruits.reverse()
for i in fruits:
    print(i)
>> cherry
>> banana
>> apple

I am trying to tokenize a string using a function by passing the char string[] and char *pointer[100]. While I have working code inside the int main(), I am having trouble actually declaring the parameters for the function.

I know how to pass the char array (char string[]), but not how to pass the char pointer array (char *pointer[100]).

This is my code below:

int main() {

   // Declare variables
   char str[] = "this is a test only - just a test";       // char array
   char *ptr1[100], *ptr2[100];                           // Creates two pointers

   function1(str, *ptr1[100]);

   return 0;
}

void function1(char str[], char *ptr1[100]) {

   int i = 0;
       int count = 0;

       // Declaration of strtok: char *strtok(char *str, const char *delim)
       // It breaks *str into a series of tokens using *delim
       char *p = strtok (str, " ");

       // Stores each piece into the array
       while (p != NULL) {
           ptr1[i++] = p;
           p = strtok(NULL, " ");
           count++;
       }

       // Prints the array
       for (i = 0; i < count; ++i) {
           printf("%s\n", ptr1[i]);
       }
}

For my code, it works if I get rid of the function and simply place the code in my int main(). Other times, I manipulated the second parameter and it started to work. However, the return values from 'p' transformed into integers from the "ptr1[i++] = p" portion of the code.

Lab Assignment 1

2020 – 2021 Fall, CMPE 211 Fundamentals of Programming II

STUDENT AFFAIRS

DUE DATE: 14.10.2020 – 23:59

In this lab, we will create a model course registration application. Please check out the example run of the program first.

You are asked to implement the classes;

• Student.

• Course.

• Grade.

• StudentAffairs. It will contain the main method.

The commands and their arguments for this week are:

• createCourse <courseCode> <capacity> <day> <studentCount> <averageGrade>

• createStudent <studentName> <studentID>

• addGradeStudent <studentID> <letterGrade>

• addGradeCourse <courseCode> <grade>

• removeGradeStudent <studentID> <letterGrade>

• removeGradeCourse <courseCode> <grade>

• averageGradeStudent <studentID>

• averageGradeCourse <courseCode>

• printGradesStudent <studentID>

• Q

where letterGrade can be (AA, BA, BB, CB, CC, DC, DD, F, FX).

In order to store the students and the courses, create 2 Arrays for them in the StudentAffairs class. You need to take commands from user until you see the “Q” command. For this purpose, you need to create while loop. Stopping condition of this command is “Q” command from user. Each command needs to be differentiated either if clause or switch case. After each command differentiated, specific information subcommands will be taken that belongs the specific main command parsed with space. Each command has specific things to do and command line output that will inform the user. Look at the demo video for better understanding. However, at first you need to create Student, Course and Grade classes.

Grade Class

Data Declarations:

• double grade Methods:
• Constructor : Constructor gets the letter grade and converts it to number representation with the method called convertLetter than holds that value within the grade variable.
• double convertLetter (String letterGrade) : Gets letter grade and returns numeric version of it. (AA=4.0, BA=3.5, BB=3.0, CB=2.5, CC=2.0, DC=1.5, DD=1.0, F=0, FX=0)

• Create Getters and Setters.

Student Class

Data Declarations:

• Grade[] Grades : Holds the Grades of the Student.

• String Name, String StudentID, int GradeCount Methods:
• Constructor : Constructor gets the name of the student and the student ID. Grade array should be initialized here as well (array size is 4). GradeCount is 0 initially.

• boolean addGrade (String letterGrade) : Adding a grade to the Grade array. Returns false if the gradeCount equals to the array size. Increase gradeCount if the grade succesfully added to the array and method should returns true.
• boolean removeGrade (int index) : Remove a grade from the Grade array with given specific index. Returns false if the gradeCount equals to the 0. Decrease gradeCount if the grade successfully removed from the array and method should returns true. Don’t forget to be shifting array after deleting element.
• String printGrades() : Returns all grades of student.

• double averageGrade() : Returns average grades of student.

• String toString( ) : The format is “<name>(<ID>)”.

• Create Getters and Setters.

Course Class

Data Declarations:

• String CourseCode, day

• int studentCount, Capacity

• double averageGrade Methods:
• Constructor : Gets all of the data declarations.

• boolean addGrade (double grade) : Adding a grade to the course. That means student count needs to increase by one. And average grade needs to be calculated. Return false if the capacity reached.
• boolean removeGrade (double grade) : Removing a grade from the course. That means student count needs to decrease by one. And average grade needs to be calculated. Return false if the student count is already 0.

• String toString( ) : The format is “<courseCode>”.

• Create Getters and Setters.
