Ex: If the input is: 40 6 1 where 40 is the number of seconds, 6 is the number of minutes, and 1 is the number of hours, the output is: 4000 seconds ▷ Run main.cpp #include 1 2 using namespace std; 3 4 int main() { 5 int seconds; int minutes Q Search Open new tab History H Warrow_forwardThe Greatest and Least of These Write a program with a loop that lets the user enter a series of integers. The user should enter-99 to signal the end of the series. After all the numbers have been entered, the program should display the largest and smallest numbers entered.

- Miles per Gallon Write a program that calculates a car's gas mileage. The program should ask the user to enter the number of gallons of gas the car can hold and the number of miles it can be driven on a full tank. It should then display the number of miles that may be driven per gallon of gas.

- Payroll Flowchart Analysis Discuss the risks depicted by the following payroll system flowchart. Describe the internal control improvements to the system that are needed to reduce these risks with specific explanations. An illustration of the above flowchart: It is represented in six columns and the column header reads: supervisor; payroll; data processing; accounts payable; cash disbursement; general ledger. In supervisor column, timekeeper enters into time cards and that leads to “Review Time cards and prepares Personnel Action Form” that further leads to two source documents “time cards, per action form.” Per action, form enters into prepare payroll in payroll column. Prepare payroll enters into paychecks and two source documents “payroll register, payroll register.” Payroll register leads to inverted triangle and payroll leads to A. Paycheck enters into review and distribute in supervisor column leads to paycheck and that further leads to employees. In data processing column,…arrow_forwardUsing the following execution shown below, explain what is done in each of the ARIES recovery algorithm phases: LSN LOG 00 begin_checkpoint 10 end_checkpoint 20 update: T1 writes P1 30 update: T2 writes P2 40 update: T3 writes P3 50 T2 commit 60 update: T3 writes P2 70 T2 end 80 update: T1 writes P5 90 T3 abort CRASH, RESTART In addition to the execution shown here, the system crashes during recovery after writing two log records to stable storage and again after writing another two log recordsarrow_forwardA new application is being developed and will be using a database that includes a relation about items: Item (item_id:integer, item_name:string, color:string, price:real). Both the purchasing department in charge of obtaining raw material and the manufacturing department in charge of manufacturing the items can change the price of manufactured items according to changes that may happen in the raw material cost or production cost. The two departments use different transactions to update the price of items. The new application uses the following sequences of actions, listed in the order they are submitted to the DBMS: Sequence S1: T1:R(X), T2:W(X), T2:W(Y), T3:W(Y), T1:W(Y), T1:Commit, T2:Commit, T3:Commit Sequence S2: T1:R(X), T2:W(Y), T2:W(X), T3:W(Y), T1:W(Y), T1:Commit, T2:Commit, T3:Commit For each of the following concurrency control mechanisms, describe how they will handle each of the sequences (S1 & S2).

- As a database administrator of a large manufacturing organization, you are in charge of their website database that handles suppliers, parts, catalog, customers, and payments of delivered items. The following relations are part of the large database: Supplier(SID, Sname, Saddress, Stelephone)Customer(CID, Cname, Caddress, Ctelephone)Part(PID, Pname, Pmodel, Pcolor)Catalog(SID, PID, Price) (The Catalog relation lists the prices charged for parts by Suppliers). Because the application is web-based and the database is accessed by many users, you want to increase the concurrency usage without compromising the data quality. For each of the following transactions, state the minimum SQL isolation level you would use in order to avoid any conflict problems in them. Please explain your choice. A transaction that adds a new part to a supplier’s catalog. A transaction that increases the price that a supplier charges for a part. A transaction that determines the total number of items for a given…arrow_forwardPlease no AI! Or if you do use AI, Check the work please! Thank you!arrow_forward(Dynamic Programming.) Recall the problem presented in Assign- ment 3 where given a list L of n ordered integers you're tasked with removing m of them such that the distance between the closest two remaining integers is maxi- mized. See Assignment 1 for further clarification and examples. As it turns out there is no (known) greedy algorithm to solve this problem. However, there is a dynamic programming solution. Devise a dynamic programming solution which determines the maximum distance between the closest two points after removing m numbers. Note, it doesn't need to return the resulting list itself. Hint 1: Your sub-problems should be of the form S(i, j), where S(i, j) returns the maximum distance of the closest two numbers when only considering removing j of the first i numbers in L. As an example if L [3, 4, 6, 8, 9, 12, 13, 15], then S(4, 1) = 2, since the closest two values of L' = [3,4,6,8] are 6 and 8 after removing 4 (note, 8-6 = = 2). = Hint 2: For the sub-problem S(i, j),…arrow_forward
