Which of the following is true about images that are arranged in a collumn

1 answer:

7 0

Figure 1: An image — an array or a matrix of pixels arranged in columns and rows. In a (8-bit) greyscale image each picture element has an assigned intensity that ranges from 0 to 255. A grey scale image is what people normally call a black and white image, but the name emphasizes that such an image will also include many shades of grey. Figure 2: Each pixel has a value from 0 (black) to 255 (white). The possible range of the pixel values depend on the colour depth of the image, here 8 bit = 256 tones or greyscales. A normal greyscale image has 8 bit colour depth = 256 greyscales. A “true colour” image has 24 bit colour depth = 8 x 8 x 8 bits = 256 x 256 x 256 colours = ~16 million colours.

Explanation:

For the linear search, the input range doesn't need to be sorted. It works on a both unsorted and sorted array.

For binary search, the input range must be sorted, otherwise, it will fail.

should variables that contain numbers always be declared as integer or floating-point data types? why or why not? name potential

Stells [14]

No, it is not necessary that variables that contain numbers should always be declared as integer or floating-point data types.

It is not necessary that variables that contain numbers should be declared as integer and floating point data types. Because number can be declared with different data types. As we know that data type is a vital aspect in programming. It describes the type of a value that is contained in a variable. It is the data type based on which memory is allocated to a number or any type of variables.

Numbers can be whole decimal/fractional, signed, unsigned, small, and long. Simply, they exist in a variety of values. According to their values range, the amount of memory is reserved.

Different programming languages offer different data types to store numbers, depending on their types and size. Let’s consider some examples of data types used in programming languages in order to declare variables holding numbers.

In Python int, float, and complex are the data types used to declare number type variables.

SQL uses INTEGER, SMALLINT , BIGINT , NUMERIC() , and DECIMAL() data types for numbers.

To deal with number type variables, Java has six predefined data types, such as int, long, short, byte, float, and double.

JavaScript uses a single data type called 'number' to declare numbers.

In C++, two fundamental data types, int and float, are used to represent numeric variables. But C++ is not only limited to these two data types. The data type char can also store numbers. Other data types for declaring numbers as variables are derived from int, float and char, such as short int, long int, signed int, unsigned int, double, long double, signed char, unsigned char etc. etc.

So in concluding remarks, declaring a number type variable is not only limited to using integers and floating-points data types. Rather it entirely depends on the respective programming language, and size and type of the number to be stored in the variable.

Write a function: function solution(N); that, given a positive integer N, prints the consecutive numbers from 1 to N, each on a

koban [17]

Answer:

The program written in Python is as follows:

def solution(N):

concat = ""

for i in range(1,N+1):

if not(i%2 == 0 or i%3 ==0 or i%5 == 0):

print(str(i))

else:

if i%2 == 0:

concat= concat+"Codility"

if i%3 == 0:

concat= concat+"Testers"

if i%5 == 0:

concat= concat+"Coders"

print(concat)

concat = ""

N = int(input("Enter a positive integer: "))

solution(N)

Explanation:

This line declares the function

def solution(N):

This line initializes a variable named concat to an empty string

concat = ""

This line iterates from 1 to the input integer

for i in range(1,N+1):

This line checks if the current number of iteration is divisible by 2,3 or 5, if no, the number is printed

if not(i%2 == 0 or i%3 ==0 or i%5 == 0):

print(str(i))

If otherwise

else:

This lines checks if current number is divisible by 2; if yes the string "Codility" is concatenated to string concat

if i%2 == 0:

concat= concat+"Codility"

This lines checks if current number is divisible by 3; if yes the string "Testers" is concatenated to string concat

if i%3 == 0:

concat= concat+"Testers"

This lines checks if current number is divisible by 2; if yes the string "Coders" is concatenated to string concat

if i%5 == 0:

concat= concat+"Coders"

The concatenated string is printed using this line

print(concat)

This variable concat is intialized back to an empty string

concat = ""

The main method starts here

N = int(input("Enter a positive integer: "))

This line calls the defined function solution

solution(N)
