Question

A programmer is creating an algorithm that will be used to turn on the motor to open the gate in a parking garage. The specifications for the algorithm are as follows. The gate should not open when the time is outside of business hours. The motor should not turn on unless the gate sensor is activated. The motor should not turn on if the gate is already open. Which of the following algorithms can be used to open the gate under the appropriate conditions?

Answer 1

The algorithm which can be used to open the gate under the appropriate conditions is:

1. Check if the time is during business hours.
2. If Yes, check if the gate sensor is activated.
3. If Yes, check if the gate is open.
4. If it is No, turn on the motor.

What is an algorithm?

An algorithm can be defined as a standard formula (procedures) which comprises a set of finite steps and instructions that is typically used for solving a problem on a computer under the appropriate conditions.

This ultimately implies that, an algorithm is a standard, logical formula (procedures) containing the step-by-step rules and instructions for performing a specific task or proffering a solution to a specific problem on a computer system.

In this scenario, the algorithm which can be used to open the gate under the appropriate conditions is:

1. Check if the time is during business hours.
2. If Yes, check if the gate sensor is activated.
3. If Yes, check if the gate is open.
4. If it is No, turn on the motor.
