Given an n-element array X, algorithm D calls algorithm E on each element X[i]. Algorithm E runs in O(i) time when it is called
krek1111 [17]

Answer:

O(n^2)

Explanation:

The number of elements in the array X is proportional to the algorithm E runs time:

For one element (i=1) -> O(1)

For two elements (i=2) -> O(2)

.

.

.

For n elements (i=n) -> O(n)

If the array has n elements the algorithm D will call the algorithm E n times, so we have a maximum time of n times n, therefore the worst-case running time of D is O(n^2)

3.14 LAB: Simple statistics for Python
Ad libitum [116K]

Answer:

Following are the correct python code to this question:

n1 = float(input('Input first number: '))#input first number  

n2 = float(input('Input second number: '))#input second number  

n3 = float(input('Input third number: '))#input third number  

n4 = float(input('Input fourth number: '))#input fourth number  

average = (n1+n2+n3+n4)/4 #calculate input number average

product = n1*n2*n3*n4 # calculate input number product

print('product: {:.0f}  average: {:.0f}'.format(round(product),round(average))) #print product and average using round function

print('product: {:.3f}  average: {:.3f}'.format(product,average)) #print product and average value

Output:

Please find the attachment.

Explanation:

The description of the above python code can be defined as follows:

  • In the above python program four variable "n1, n2, n3, and n4" is defined, in which we take input from the user end, and in these user inputs we use the float method, that converts all the input value in to float value.
  • In the next step, two variable average and product are defined, that calculate all input numbers product, average, and hold value in its variable.
  • In the last line, the print method is used, which prints its variable value by using a round and format method.

Write a function string middle(string str) that returns a string containing the middle character in str if the length of str is
Katen [24]

Answer:

function getMiddle(s) {

return s.length % 2 ? s.substr(s.length / 2, 1) : s.substr((s.length / 2) - 1, 2);

}

// I/O stuff

document.getElementById("submit").addEventListener("click", function() {

input = document.getElementById("input").value;

document.getElementById("output").innerHTML = getMiddle(input);

});

Explanation:

// >>> is an unsigned right shift bitwise operator. It's equivalent to division by 2, with truncation, as long as the length of the string does not exceed the size of an integer in Javascript.

// About the ~ operator, let's rather start with the expression n & 1. This will tell you whether an integer n is odd (it's similar to a logical and, but comparing all of the bits of two numbers). The expression returns 1 if an integer is odd. It returns 0 if an integer is even.

// If n & 1 is even, the expression returns 0.

// If n & 1 is odd, the expression returns 1.

// ~n & 1 inverts those two results, providing 0 if the length of the string is odd, and 1 if the length of the sting is even. The ~ operator inverts all of the bits in an integer, so 0 would become -1, 1 would become -2, and so on (the leading bit is always the sign).

// Then you add one, and you get 0+1 (1) characters if the length of the string is odd, or 1+1 (2) characters if the length of the string is even.

Write a statement to add the key Tesla with value USA to car_makers. Modify the car maker of Fiat to Italy. Sample output for th
marishachu [46]

Answer:

Input code:

car_makers = {'Honda': 'Japan', 'Fiat': 'Germany'}

#add Tesla and USA as corresponding value

car_makers['Tesla'] = 'USA'

#change Fiat entry to Italy instead of Germany

car_makers['Fiat'] = 'Italy'

print(car_makers)

print('Honda made in', car_makers['Honda'])

print('Fiat made in', car_makers['Fiat'])

print('Tesla made in', car_makers['Tesla'])

Explanation:

The first line is a define object in the python code, containing two entries of Honda and Fiat and their respective countries.

The python code adds an entry to the object "car maker" using the bracket notation, the tesla car from USA.

The country of the Fiat car is changed from Germany to Italy, using the bracket notation.

The output of the complete object and the individual cars is given.

<u>output of the python code:</u>

{'Honda': 'Japan', 'Fiat': 'Italy', 'Tesla': 'USA'}

Honda made in Japan

Fiat made in Italy

Tesla made in USA.
