A device is to be installed to control elevators in a building with several floors. The system will use the following logic/rules to move elevators between floors: ● Each elevator has a set of m buttons, one for each floor. These illuminate when pressed and cause the elevator to visit the corresponding floor. The illumination is canceled when the elevator visits the corresponding floor. ● Each floor, except the first floor and top floor has two buttons, one to request an up-elevator and one to request a down-elevator. These buttons illuminate when pressed. The illumination is canceled when an elevator visits the floor and then moves in the desired direction. ● When an elevator has no requests, it remains at its current floor with its doors closed. The basic course of Action for an elevator scenario is: 1. Passenger presses the floor button (that is the button on the wall). 2. Elevator system detects the floor button pressed. 3. Elevator moves to the floor. 4. Elevator doors open. 5. Passenger gets in and presses the elevator button (that is the button in the cabin panel). 6. Elevator doors close. 7. Elevator moves to the required floor. 8. Elevator doors open. 9. Passenger gets out. 10. Elevator doors close. Draw the Sequence diagram representing the use of the floor button i.e., from the passenger pressing the floor button until the elevator arrives, and they enter the elevator
Operations
In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.
Basic Operators
An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.
Division Operator
We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:
Modulus Operator
Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.
Operators
In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.

The system will use the following logic/rules to move elevators between floors:
● Each elevator has a set of m buttons, one for each floor. These illuminate
when pressed and cause the elevator to visit the corresponding floor. The
illumination is canceled when the elevator visits the corresponding floor.
● Each floor, except the first floor and top floor has two buttons, one to
request an up-elevator and one to request a down-elevator. These buttons
illuminate when pressed. The illumination is canceled when an elevator
visits the floor and then moves in the desired direction.
● When an elevator has no requests, it remains at its current floor with its
doors closed.
The basic course of Action for an elevator scenario is:
1. Passenger presses the floor button (that is the button on the wall).
2. Elevator system detects the floor button pressed.
3. Elevator moves to the floor.
4. Elevator doors open.
5. Passenger gets in and presses the elevator button (that is the button in the
cabin panel).
6. Elevator doors close.
7. Elevator moves to the required floor.
8. Elevator doors open.
9. Passenger gets out.
10. Elevator doors close.
