Answer:

import random

decisions = int(input("How many decisions: "))

for i in range(decisions):

   number = random.randint(0, 1)

   if number == 0:

       print("heads")

   else:

       print("tails")

Explanation:

*The code is in Python.

import the random to be able to generate random numbers

Ask the user to enter the number of decisions

Create a for loop that iterates number of decisions times. For each round; generate a number between 0 and 1 using the randint() method. Check the number. If it is equal to 0, print "heads". Otherwise, print "tails"

Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combinin
Dmitry_Shevchenko [17]

Answer:

Follows are the code to this question:

#include<iostream>//defining header file

using namespace std;// use package

int main()//main method

{

int red,green,blue,x;//declaring integer variable

cin>> red >>green>>blue;//use input method to input value

if(red<green && red<blue)//defining if block that check red value is greater then green and blue  

{

x = red;//use x variable to store red value

}

else if(green<blue)//defining else if block that check green value greater then blue  

{

x= green; //use x variable to store green value

}

else//defining else block

{

x=blue;//use x variable to store blue value

}

red -= x;//subtract input integer value from x  

green -=x; //subtract input integer value from x

blue -= x;//subtract input integer value from x

cout<<red<<" "<<green<<" "<<blue;//print value

return 0;

}

Output:

130 50 130

80 0 80

Explanation:

In the given code, inside the main method, four integers "red, green, blue, and x" are defined, in which "red, green, and blue" is used for input the value from the user end. In the next step, a conditional statement is used, in the if block, it checks red variable value is greater than then "green and blue" variable. If the condition is true, it will store red variable value in "x", otherwise, it will goto else if block.

  • In this block, it checks the green variable value greater than the blue variable value. if the condition is true it will store the green variable value in x variable.
  • In the next step, else block is defined, that store blue variable value in x variable, at the last step input variable, is used that subtracts the value from x and print its value.

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 function called sum_scores. It should take four arguments, where each argument is the team's score for that quarter. It
saw5 [17]

Answer:

Here is the Python program which has a function sum_scores:

def sum_scores(score1, score2, score3, score4):

   sum = score1 + score2 + score3 + score4

   print(sum)    

sum_scores(14,7,3,0)

Explanation:

  • Method sum_scores takes four arguments, score1, score2, score3, score4.
  • The sum variable adds these four scores and stores the value of their addition.
  • Lastly print statement is used to print the value stored in sum variable which is the value obtained by adding the four scores.
  • Last statement calls the sum_scores method and passes four values to it which are 14,7,3,0
  • The output of the above program is:
  • 24
  • If you want to use return statement instead of print statement you can replace print(sum) with return sum. But in order to display the sum of the scores you can replace sum_scores(14,7,3,0) with print(sum_scores(14,7,3,0))
  • The program along with the output is attached as a screenshot.

A city government is attempting to reduce the digital divide between groups with differing access to computing and the Internet.
sergeinik [125]

Answer:

C

Explanation:

Putting all government forms on the city web site is the least activity likely to be effective in the purpose of reducing digital divide.

Holding basic computer classes at the community centers will very much help to reduce the digital divide.

Providing free wireless internet connections at locations in low-income neighborhood will also reduce the gap of digital divide

Requiring that every city school has computers that meet a minimum hardware and software will made computing resources available to users thereby reducing digital divide.

Write a function summarize_letters that receives a string and returns a list of tuples containing the unique letters and their f
marysya [2.9K]

Answer:

Explanation:

2nd part

def summarize_letters(string):

#Initializaing a empty dictionary

character_counter = {}

#converting all the characters to lowercase

string_lower = string.lower()

for i in string_lower:

#checking if the chacter presents in the dictionary then increase it by one and also to check if the character is alphabet

if i in character_counter and i.isalpha():

character_counter[i] = character_counter[i]+1

#checking if the character not present in the dictionary then assign 1

if i not in character_counter and i.isalpha():

character_counter[i] = 1

#converting the dictionary to list of tuples

list_of_tuples = [(k, v) for k, v in character_counter.items()]

return list_of_tuples

#3rd Part

#initializing a string of characters in alphabets

alphabets = 'a b b b b B A c e f g d h i j k B l m M n o p q r s P t u v w x y z'

print(summarize_letters(alphabets))

#importing the string module

import string

#pulling all the alphabets

alphabet = set(string.ascii_lowercase)

#checking if our hardcoded string has all the alphabets

if set(alphabets.lower()) >= alphabet:

print('The string ' +alphabets+' has all the letters in the alphabet ')
