Q4. Cause of overflow Error (1D, binary math) - Tara Sehdave
In a certain computer program, two positive integers are added together, resulting in an overflow error. Which of the following best explains why the error occurs?
Responses
A
The program attempted to perform an operation that is considered an undecidable problem.
B The precision of the result is limited due to the constraints of using a floating-point representation.
C The program can only use a fixed number of bits to represent integers; the computed sum is greater than the maximum representable value.
D The program cannot represent integers; the integers are converted into decimal approximations, leading to rounding errors.
The correct answer is C because…
- Overflow error occurs in a computer program when adding two positive integers.
- The program uses a fixed number of bits to represent integers.
- The sum of the two integers exceeds the maximum representable value within the fixed number of bits.
- Due to this limitation, the program cannot accurately represent the result of the addition.
- As a result, an overflow error is triggered to indicate that the computed sum is beyond the representable range.
# python overflow example
# as a popcorn hack (binary challenge), describe an overflow in 8 binary digits
# Add 1 to 11111111 (255)
# Subtract 1 from 00000000 (0)
# Try overflow and underflow here: https://nighthawkcoders.github.io/teacher_portfolio/c4.4/2023/09/14/javascript-binary-U2-1.html
import sys
# Maximum float
max_float = sys.float_info.max
print(f"Max float: {max_float}")
# Attempt to overflow float
overflow_float = max_float * 2
print(f"Overflow float to infinity: {overflow_float}")
Max float: 1.7976931348623157e+308
Overflow float to infinity: inf
Popcorn Hack:
The binary overflow is the computer trying to go to a number that is past the amount of memory the computer is storing so it can’t get all the numbers. This causes the computer to just shut down the number as it can’t compute the final number.
Overflow will happen when trying to add 1 to 11111111 which is already 255. When subtracting 1 from 00000000 which is already 0, this will lead to underflow.
Q5. Inputs to Logic Circuit (2D, binary logic) - Hanlun Li
The diagram below shows a circuit composed of three logic gates. Each gate takes two inputs and produces a single output. For which of the following input values will the circuit have an output of true ?
The diagram in question shows a circuit composed of three logic gates. Each gate takes two inputs and produces a single output.
For which of the following input values will the circuit have an output of true ?
A) A = true, B = true, C = true, D = false
B) A = true, B = false, C = false, D = true
C) A = false, B = true, C = true, D = true
D) A = false, B = false, C = true, D = true
A OR B = True, C AND D = True, and since True AND True = True, C is correct.
OR gate only returns true if one of the values is true, and the AND gate returns true if both values are true.

Q11. Color represented by binary Triplet (2D, binary) - Torin Wolff
A color in a computing application is represented by an RGB triplet that describes the amount of red, green, and blue, respectively, used to create the desired color. A selection of colors and their corresponding RGB triplets are shown in the following table. Each value is represented in decimal (base 10).
According to information in the table, what color is represented by the binary RGB triplet (11111111, 11111111, 11110000) ?
What is a binary triplet?
A binary triplet is a set of three binary numbers. Binary numbers are numbers that are represented by a series of 1’s and 0’s. Binary numbers are used in computers because they are easy to represent with electrical signals. A binary triplet is a set of three binary numbers that are used to represent a color. The first number represents the amount of red in the color, the second number represents the amount of green in the color, and the third number represents the amount of blue in the color. The numbers are represented in binary because it is easy to represent with electrical signals. The numbers are represented in a triplet because it is easy to represent with electrical signals.
How is a color in binary represented?
A color in binary is represented by a set of three binary numbers. The first number represents the amount of red in the color, the second number represents the amount of green in the color, and the third number represents the amount of blue in the color. The numbers are represented in binary because it is easy to represent with electrical signals. The numbers are represented in a triplet because it is easy to represent with electrical signals. An example of this would be: (01101110, 11111111, 10010110), if you converted this binary triplet to a decimal number it would be 110, 255, 150. This would be a shade of the color green.
How do you convert a binary triplet to a decimal number?
To convert a binary string to a decimal number you need to multiply each digit by its place value. For example, if you have the binary string 1010 you would multiply the first digit by 2^3, the second digit by 2^2, the third digit by 2^1, and the fourth digit by 2^0. This would give you the decimal number 10. To convert a binary triplet to a decimal number you need to multiply each digit by its place value. For example, if you have the binary triplet (01101110, 11111111, 10010110) you would multiply the first digit by 2^7, the second digit by 2^6, the third digit by 2^5, the fourth digit by 2^4, the fifth digit by 2^3, the sixth digit by 2^2, the seventh digit by 2^1, and the eighth digit by 2^0. This would give you the decimal number 110, 255, 150.
(0 * 2^7) + (1 * 2^6) + (1 * 2^5) + (0 * 2^4) + (1 * 2^3) + (1 * 2^2) + (1 * 2^1) + (0 * 2^0)
= 0 + 64 + 32 + 0 + 8 + 4 + 2 + 0
= 110

Q50. Reasonable time algorithms (1D, Big O) - Vance Reynolds
Consider the following algorithms. Each algorithm operates on a list containing n elements, where n is a very large integer.
- An algorithm that accesses each element in the list twice
- An algorithm that accesses each element in the list n times
- An algorithm that accesses only the first 10 elements in the list, regardless of the size of the list
Which of the algorithms run in reasonable time? Answer D is correct because in order for an algorithm to run in reasonable time, it must take a number of steps less than or equal to a polynomial function.
- Algorithm I accesses elements times (twice for each of n elements), which is considered in time.
- Algorithm II accesses elements (n times for each of n elements), which is in reasonable time.
- Algorithm III accesses 10 elements, which is in reasonable time.
Simple Explainations:
Unreasonable time: Algorithms with exponential or factorial efficiencies are examples of algorithms that run in an unreasonable amount of time.
Reasonable time: Algorithms with a polynomial efficiency or lower (constant, linear, square, cube, etc.) are said to run in a reasonable amount of time.

Q56. Compare execution times of tow version (1D analysis) - Kayden Le
An online game collects data about each player’s performance in the game. A program is used to analyze the data to make predictions about how players will perform in a new version of the game.
The procedure GetPrediction (idNum) returns a predicted score for the player with ID number idNum. Assume that all predicted scores are positive. The GetPrediction procedure takes approximately 1 minute to return a result. All other operations happen nearly instantaneously.
Two versions of the program are shown below.
Which of the following best compares the execution times of the two versions of the program?
Version I calls the GetPrediction procedure once for each element of idList, or four times total. Since each call requires 1 minute of execution time, version I requires approximately 4 minutes to execute. Version II calls the GetPrediction procedure twice for each element of idList, and then again in the final display statement. This results in the procedure being called nine times, requiring approximately 9 minutes of execution time.
Both versions aim to achieve the same result, which is to find and display the highest predicted score among the players in idList. However, Version I directly updates the highest score (topScore), while Version II updates the ID of the player with the highest score (topID) and then retrieves the predicted score for that player. Version II essentially avoids calling GetPrediction multiple times for the same ID.
The answer: D - Version II requires approximately 5 more minutes to execute than version I
# Simulate the time taken by GetPrediction, calling an expensive operation twice is slow
# as a popcorn hack (coding challenge)
# measure the time to calulate fibonacci sequence at small and large numbers
# `this task will require a code layout and a time measurement
# there are fast ways and slow ways to calculate fibonacci sequence`
'''
The GetPrediction function is a simulation stand-in for a potentially expensive operation.
In a real-world scenario, this could be a call to a;
- machine learning model
- a database query
- fibonacci sequence at a large number
- or any other algorithm that takes a significant amount of time.

Explanation
For procedures A, the procedure repeatedly adds 2 to result five times, resulting in the intended product 10. Vice versa for C. IF you want to return the result and get a correct answer, multiplying 2,-5 and -2,-5 will give you the wanted result. The following procedure is intended to return the value of x times y, where x and y are integers. Multiplication is implemented using repeated additions. A and C fit these requirements.

Q65. Call to concat and substring (4B string operations) - Ameer Hussain
A program contains the following procedures for string manipulation.
Which of the following can be used to store the string “jackalope” in the string variable animal ?
Select two answers.
Correct Answer C: animal ← Substring(“jackrabbit”, 1, 4) extracts “jack” from “jackrabbit”. animal ← Concat(animal, “a”) appends “a” to “jack”, resulting in “jacka”. animal ← Concat(animal, Substring(“antelope”, 5, 4)) extracts “lope” from “antelope” and appends it to “jacka”, resulting in “jackalope”.
Incorrect Answer D: animal ← Substring(“jackrabbit”, 1, 4) extracts “jack” from “jackrabbit”. animal ← Concat(animal, “a”) appends “a” to “jack”, resulting in “jacka”. animal ← Concat(Substring(“antelope”, 5, 4), animal) is slightly misleading because it extracts “lope” from “antelope” and should prepend it to “jacka”, but this is incorrect because it would result in “lopejacka”. the operations in Answer D would not result in “jackalope”.
animal ← Substring(“antelope”, 5, 4) would assign the substring “lope” from “antelope” to the variable animal. animal ← Concat(“a”, animal) would then prepend “a” to “lope”, resulting in “alope”. animal ← Concat(Substring(“jackrabbit”, 1, 4), animal) would take the substring “jack” from “jackrabbit” and then concatenate it with “alope” resulting in “jackalope”.
The process outlined in Answer B does indeed result in the string “jackalope”, with the first step isolating “lope” from “antelope”, the second step creating the string “alope” by prepending “a” to “lope”, and the final step creating the correct string by prepending “jack” to “alope”.
animal ← Substring(“antelope”, 5, 4) would assign the substring “lope” from “antelope” to the variable animal. animal ← Concat(“a”, animal) would then prepend “a” to “lope”, resulting in “alope”. animal ← Concat(Substring(“jackrabbit”, 1, 4), animal) would take the substring “jack” from “jackrabbit” and then concatenate it with “alope” resulting in “jackalope”.

# Incorrect Answer D
# as a popcorn hack (binary challenge), create string and concatenation options for A, B, C
animal = "jackrabbit"[0:4] # Substring("jackrabbit", 1, 4)
animal += "a" # Concat(animal, "a")
animal = "antelope"[4:8] + animal # Concat(Substring("antelope", 5, 4), animal)
print(animal) # Outputs: lopejacka
lopejacka
