If you are writing an algorithm and you aren’t confident that you understand the problem, what can you do?
Answers
Answer:
divide it into smaller pieces
Explanation:
Usually, the main reason a programmer does not understand a problem fully is that there is too much information. The best way to try and fully understand a problem is to divide it into smaller pieces. Start off by answering the question what is the expected output for an input. Then divide each individual issue within the problem. This will allow you as a programmer/developer to create an individual solution for each individual issue within the problem and then test to make sure that the input gives the correct output.
company gives the following discount if you purchase a large amount of supply. Units Bought Discount 10 - 19 20% 20 - 49 30% 50 - 99 35% 100 40% If each item is $4.10. Create a program that asks the user how many items they want to buy, then calculates the pre-discount price, the amount of discount and the after discount price. So for example if order 101 items, I should see something similar to the following: With your order of 101 items, the total value will be $414.10 with a discount of $165.64 for a final price of $248.46. Your output should be very well organized, and use the correct formatting. (Including precision)
Answers
Answer:
In Python:
order = int(input("Order: "))
discount = 0
if(order >= 10 and order <20):
discount = 0.20
elif(order >= 20 and order <50):
discount = 0.30
elif(order >= 50 and order <100):
discount = 0.35
elif(order >= 100):
discount = 0.40
price = order * 4.1
discount = discount * price
print("With your order of "+str(order)+" items, the total value will be $"+str(round(price,2))+" with a discount of $"+str(round(discount,2))+" for a final price of $"+str(round((price-discount),2)))
Explanation:
This prompts the user for number of orders
order = int(input("Order: "))
This initializes the discount to 0
discount = 0
For orders between 10 and 19 (inclusive)
if(order >= 10 and order <20):
-----------discount is 20%
discount = 0.20
For orders between 20 and 49 (inclusive)
elif(order >= 20 and order <50):
-----------discount is 30%
discount = 0.30
For orders between 50 and 99 (inclusive)
elif(order >= 50 and order <100):
-----------discount is 35%
discount = 0.35
For orders greater than 99
elif(order >= 100):
-----------discount is 40%
discount = 0.40
This calculates the total price
price = order * 4.1
This calculates the pre discount
discount = discount * price
This prints the report
print("With your order of "+str(order)+" items, the total value will be $"+str(round(price,2))+" with a discount of $"+str(round(discount,2))+" for a final price of $"+str(round((price-discount),2)))
Write a program that plays the popular scissor-rockpaper game. (A scissor can cut a paper, a rock can knock a scissor, and a paper can wrap a rock.) The program randomly generates a number 0, 1, or 2 representing scissor, rock, and paper. The program prompts the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer wins, loses, or draws. Here are sample runs:
scissor (0), rock (1), paper (2): 1
The computer is scissor. You are rock. You won
scissor (0), rock (1), paper (2): 2
The computer is paper. You are paper too. It is a draw

What is computer programming?Computer programming is defined as the process of carrying out a specific computation, typically through creating an executable computer program. Computer programmers create code and scripts, modify them, and test them to make sure that software and applications function as intended. They convert the blueprints made by engineers and software developers into computer-readable instructions.
The algorithm determines whether the key the number you're looking for and the array's middle value are equal. If so, the key is in the middle and the search is complete. The program then determines if the key is larger or less than the middle value if it isn't.
Thus, PRE: True POST: is Sorted(a) An > 1 C) PRE : n > 1A is Sorted (a). 10 sxs a[n-1] POST: result == x E a vissorted (a).

Explanation:
A perpetual system of inventory can be defined as a method of financial accounting, which involves the updating informations about an inventory on a continuous basis (in real-time) as the sales or purchases are being made by the customers, through the use of enterprise management software applications and a digitized point-of-sale (POS) equipment.
Under a perpetual system of inventory, updates of the journal entry for cost of goods sold or received would include debiting accounts receivable and crediting sales immediately as it is being made or happening.
Hence, an advantage of the perpetual system of inventory over the periodic system of inventory is that, it ensures the inventory account balance is always accurate provided there are no spoilage, theft etc.
The following are the characteristic of a perpetual inventory system;
I. It is the most popular choice for modern business.
II. Inventory is updated in near real-time.
III. It provides up-to-date balance information and requires fewer physical counts.
Consider the following class definition.

The following statement appears in a method in a class other than Tester. It is intended t o create a new Tester object t with its attributes set to 10 and 20.
Tester t = new Tester(10,20);
Which can be used to replace / missing constructor / so that the object t is correctly created?
Answers
Answer:
Explanation:
The following constructor needs to be added to the code so that the object called t can be created correctly...
public Tester(int arg1, int arg2) {
num1 = arg1;
num2 = arg2;
}
This basic constructor will allow the object to be created correctly and will take the two arguments passed to the object and apply them to the private int variables in the class. The question does not state what exactly the Tester constructor is supposed to accomplish so this is the basic format of what it needs to do for the object to be created correctly.

Assume that you are able to do an exhaustive search for the key to an encrypted message at the rate of 100 Million trials per second. (a) (7 Points) How long in (days or years) would it take for you to find the key on the average to a code that used 112-bit key on average
Answers
Answer:
8.22 × 10²⁰ years
Explanation:
Given that:
Total frequency = 100 million per record
The length of the key used for the encryption = 112 bit key
To calculate the number of seconds in a year, we have:
= 365 × 24 × 60 × 60
= 3.1536 × 10⁷ seconds
Thus, on average, the number of possible keys that is required to check for the decryption should be at least 2¹¹¹ keys.
[tex]\mathbf{ = \dfrac{2^{111} \times 10^6}{3.1536 \times 10^7} = 8.22 \times 10^{20} \ years}[/tex]
Thus, it will take a total time of about 8.22 × 10²⁰ years on average.

What is undecidable problem?Problems that cannot be solved by an algorithm are known as undecidable problems since no computer program can come up with a solution that works for every scenario.
This is a key drawback of computing systems, and it has been analytically shown that some issues are intractable from the start.
Decision issues that lack an algorithmic solution are referred to as undecidable.
A issue that cannot be solved by a computer or computer software of any type has never been solved by a computer. There is no such thing as a Turing machine that can solve an insoluble problem.
