Mining safety sensors may create up to 2.4 terabits (TB) of data every minute.

Sensors can help to improve the world by improving diagnostics in medical applications, the performance of energy sources such as fuel cells, batteries, and safety, solar power, people's health, and security, sensors for exploring space and the known university, and improved environmental monitoring.

Sensors play an important role in industrial applications such as process control, monitoring, and safety. The change in sensor output compared to a unit change in input is measured as sensitivity.

It provides several advantages, including increased sensitivity during data gathering, practically lossless transmission, and continuous, real-time analysis.

Real-time feedback and data analytics services ensure that processes are operational and being carried out optimally. Sensors in a single smart-connected house may generate up to 1 gigabit (GB) of data every week.

Answer:

The  program in Python is as follows:

nums = []

for i in range(3):

   num = int(input(""))

   nums.append(num)

print(min(nums))

Explanation:

This initializes a list of numbers

nums = []

This loop is repeated 3 times

for i in range(3):

For each repetition, this prompts the user for input

   num = int(input(""))

This appends the input to the list

   nums.append(num)

This gets the smallest of the three inputs using the min() function. The smallest is also printed

print(min(nums))

The Answer is in Bold:

The method in Java is as follows:

public static ArrayList<Integer> appendPosSum(ArrayList<Integer> nums) {

   int sum = 0;

   ArrayList<Integer> newArr = new ArrayList<>();

   for(int num : nums) {

       if(num>0){

           sum+=num;

           newArr.add(num);        }    }

   newArr.add(sum);

   return newArr;

 }

Explanation:

This defines the method; it receives an integer arraylist as its parameter; nums

public static ArrayList<Integer> appendPosSum(ArrayList<Integer> nums) {

This initializes sum to 0

   int sum = 0;

This declares a new integer arraylist; newArr

   ArrayList<Integer> newArr = new ArrayList<>();

This iterates through nums

   for(int num : nums) {

If current element is greater than 0

       if(num>0){

This sum is taken

           sum+=num;

And the element is added to newArr

           newArr.add(num);        }    }

At the end of the iteration; this adds the calculated sum to newArr  

newArr.add(sum);

This returns newArr

   return newArr;

 }

The following code is written in Python. It creates the parent class Shape and the three subclasses Rectangle, Square, and Circle that extend Shape. Shape has the constructor which is empty and the area method which returns 0.0, while the three subclasses take in the necessary measurements for its constructor. Each subclass also has getter and setter methods for each variable and an overriden area() method which returns the shapes area.

class Shape:

   def __init__(self):

       pass

   def area(self):

       return 0.0

class Square(Shape):

   _length = 0

   _width = 0

   def __init__(self, length, width):

       self._width = width

       self._length = length

   def area(self):

       area = self._length * self._width

       return area

   def get_length(self):

       return self._length

   def get_width(self):

       return self._width

   def set_length(self, length):

       self._length = length

   def set_width(self, width):

       self._width = width

class Rectangle(Shape):

   _length = 0

   _width = 0

   def set_length(self, length):

       self._length = length

   def set_width(self, width):

       self._width = width

class Circle(Shape):

   _radius = 0

   def __init__(self, radius):

       self._radius = radius

   def area(self):

       area = 2 * 3.14 * self._radius

A list of linked data structures is a sequence of linked data structures.

The Linked List is an array of links containing items. Each link contains a link to a different link. The second most frequently used array is the Linked List.

Explanation:

Create a node class with 2 attributes: the data and the following. Next is the next node pointer.

Create an additional class with two attributes: head and tail.

AddNode() adds to the list a new node:

Make a new node.

He first examines if the head is equal to zero, meaning that the list is empty.

The head and the tail point to the newly added node when this list is vacant.

If the list isn't empty, the new node will be added at the end of the list to point to the new node of tail. This new node is the new end of the list.

Show() will show the nodes in the list:

Set a node current that first points to the list header.

Cross the list until the current null points.

Show each node by referring to the current in each iteration to the next node.
