Answer:
Cogs and Calculators
It is a measure of the brilliance of the abacus, invented in the Middle East circa 500 BC, that it remained the fastest form of calculator until the middle of the 17th century. Then, in 1642, aged only 18, French scientist and philosopher Blaise Pascal (1623–1666) invented the first practical mechanical calculator, the Pascaline, to help his tax-collector father do his sums. The machine had a series of interlocking cogs (gear wheels with teeth around their outer edges) that could add and subtract decimal numbers. Several decades later, in 1671, German mathematician and philosopher Gottfried Wilhelm Leibniz (1646–1716) came up with a similar but more advanced machine. Instead of using cogs, it had a "stepped drum" (a cylinder with teeth of increasing length around its edge), an innovation that survived in mechanical calculators for 300 hundred years. The Leibniz machine could do much more than Pascal's: as well as adding and subtracting, it could multiply, divide, and work out square roots. Another pioneering feature was the first memory store or "register."
Apart from developing one of the world's earliest mechanical calculators, Leibniz is remembered for another important contribution to computing: he was the man who invented binary code, a way of representing any decimal number using only the two digits zero and one. Although Leibniz made no use of binary in his own calculator, it set others thinking. In 1854, a little over a century after Leibniz had died, Englishman George Boole (1815–1864) used the idea to invent a new branch of mathematics called Boolean algebra. [1] In modern computers, binary code and Boolean algebra allow computers to make simple decisions by comparing long strings of zeros and ones. But, in the 19th century, these ideas were still far ahead of their time. It would take another 50–100 years for mathematicians and computer scientists to figure out how to use them (find out more in our articles about calculators and logic gates).
Explanation:
Write a java program to read elements in an array from user and count total number of duplicate elements in array.
Answer:
Explanation:
The following code is written in Java and is a function/method that takes in an int array as a parameter. The type of array can be changed. The function then creates a counter and loops through each element in the array comparing each one, whenever one element is found to be a duplicate it increases the counter by 1 and moves on to the next element in the array. Finally, it prints out the number of duplicates.
public static int countDuplicate (int[] arr) {
int count = 0;
for(int i = 0; i < arr.length; i++) {
for(int j = i + 1; j < arr.length; j++) {
if(arr[i] == arr[j])
count++;
}
}
return count;
}

What is programming?A form of computer programming language known as procedural programming describes a number of well-planned actions and processes during the course of its development.
It includes statements, functions, and commands that are organized systematically to finish a computing task or program. Its main focus is on developing procedures.
While object-oriented programming is a type of programming where the emphasis is on generating objects as opposed to actions and data or logic. Inheritance, polymorphism, abstraction, and encapsulation are its four guiding concepts.
Therefore, the correct option is b, if 13 <= item <= 19

What is an array?A group of identical objects or pieces of data held near to one another in memory is referred to as an array. An array type is a user-defined data type that consists of an ordered collection of objects of a single data type. Ordinary array types have a set maximum number of elements they can hold and use the ordinal position as the array index.
The unordered list that is a part of the simple array is thus visible. The unordered list can be converted to an ordered list by executing the command "aList. sort()".
So, the next line will be:
>>> aList = [12, 3, 5, 7, 7]
>>> aList.index(7)
3
Therefore, the correct option is c. 3.

What routing protocol is the most popular distance-vector routing algorithm used to determine the best routes within a network
Answer:
RIP
Explanation:
RIP is a routing protocol that stands for Routing Information Protocol. It is a distance-vector routing algorithm which uses a hop count for routing its metric. RIP is the most popular and frequently used on internet. RIP uses hop count, which means it goes from low hop count to high hop count.
Therefore, it is the Routing Infomation Protocol which is the most popular distance-vector routing algorithm used to determine the best routes within a network.

Create a code for playing blackjack
The first part of the code will create two variable.
One for the first card you’re dealt and one for the second.
Add those two variable for the total score you have
Then
Create a while loop that will stop if your score becomes above 21 or if the user says that they wish to stay.
Inside the while loop have ask the user if they want to hit or stay. Inside of the question be sure to print the current total that the user has
If the user inputs “hit” add a random number between 1 and 11 to their score.
If they input “stay” then print their final score
Then
Create a code for the dealer
The dealer should also start with two cards (remember you can always copy and paste and then edit your code)
Create a while loop for the dealer. (there is rule that dealers must always hit if their total is 16 or under
Print the dealers score once they are done.
Finally
Check if your score is higher than the dealer’s.
If it is you win
If not, you lose
Remember.
If either the dealer or you reach over 21 then that person automatically loses
Answer:
import random
is_stay = 'n'
y_fcard = random.randint(1, 11)
y_scard = random.randint(1, 11)
d_fcard = random.randint(1, 11)
d_scard = random.randint(1, 11)
you_score = y_fcard + y_scard
dealer_s = d_fcard + d_scard
print("Your score", you_score)
print("dealer's score", dealer_s)
while is_stay == 'n':
if you_score > 21:
break
you_score += random.randint(1, 11)
print("Your score", you_score)
is_stay = input("Do you want to stay y/n?: ")
if you_score > 21:
print("You lost")
quit()
while dealer_s <= 16:
dealer_s += random.randint(1, 11)
if dealer_s > 21:
print("The dealer lost")
quit()
if you_score > dealer_s:
print("You are the winner", "My score: ",you_score, "\nDealer's score: ", dealer_s)
else:
print("Sorry, you lost the game", "My score: ",you_score, "\nDealer's score: ", dealer_s)
Explanation:
The python program uses the random module's 'randint' to get a random integer number between 1 and 11, and adds the value to the user's score if the user decides to hit but compares the result with the dealer's if the user stays.

movie= 'Star Wars'
String
movieID=132
int
movieAwards = ('Oscar', 'Golden Globe', 'Director's Guild')
Tuple
movieRatings = {5:'language', 3:'violence'}
Dictionary
Explanation:
movieCost = 4.95
movieCost is of float type because it has a decimal point.
movieStars = ['Carrie Fisher', 'Harrison Ford']
movieStars if of list type because in Python the elements of list is inside square brackets.
List is an ordered collection. List is mutable i-e items can be added and remved from the list
movie = 'Star Wars'
movies is a string type because it is in enclosed in single quotes only.
movieID = 132
movieID is of int type because it is only number, without decimal value.
movieAwards = ('Oscar', 'Golden Globe', 'Director's Guild')
movieAwards is a tuple type because it is enclosed in round brackets or parenthesis.
Tuple is a sequence object. It is ordered collection of item. it is immutable.
movieRatings = {5:'language', 3:'violence'}
MovieRating is a dictionay type because it is in key-value pair. it is an unordered collection.
