3.5 HACKS
Student led teaching on Abstraction. Teaching how various data types can use abstraction for computational efficiency.
PYTHON pop HACK 1:
def check_number():
try:
number = float(input("Please enter a number: "))
if number < 0:
print("The number is negative.")
else:
print("The number is non-negative.")
except ValueError:
print("Invalid input! Please enter a valid number.")
check_number()
The number is non-negative.
PYTHON pop HACK 2:
def check_scores(score1, score2):
if score1 >= 70 and score2 >= 70:
print("The student passed both subjects.")
else:
print("The student did not pass both subjects.")
score1 = float(input("Enter the first score: "))
score2 = float(input("Enter the second score: "))
check_scores(score1, score2)
The student did not pass both subjects.
PYTHON pop HACK 3:
def check_vowel(char):
vowels = 'aeiou'
if char.lower() in vowels:
print(f"The character '{char}' is a vowel.")
else:
print(f"The character '{char}' is not a vowel.")
char = input("Enter a character: ")
if len(char) == 1:
check_vowel(char)
else:
print("Please enter a single character.")
The character 'a' is a vowel.
PYTHON HW HACK 1:
def truth_table():
print("A B not (A and B) not A or not B")
print("-------------------------------------------")
values = [True, False]
for A in values:
for B in values:
result1 = not (A and B)
result2 = not A or not B # Applying De Morgan's Law
print(f"{A} {B} {result1} {result2}")
# Calling the function to print the truth table
truth_table()
A B not (A and B) not A or not B
-------------------------------------------
True True False False
True False True True
False True True True
False False True True
PYTHON HW HACK 2:
import random
def guessing_game():
print("Welcome to the guessing game!")
print("You need to guess if two statements are True or False.")
condition1 = random.choice([True, False])
condition2 = random.choice([True, False])
print("\nIs the first condition True? (yes/no)")
guess1 = input().strip().lower() == 'yes'
print("Is the second condition True? (yes/no)")
guess2 = input().strip().lower() == 'yes'
# Using De Morgan's Law to simplify the losing condition
if not (condition1 or condition2): # Equivalent to `not condition1 and not condition2`
print("Both conditions were False. You lose!")
else:
if guess1 == condition1 and guess2 == condition2:
print("Congratulations! You guessed both conditions correctly!")
else:
print("Sorry! You guessed wrong. The correct conditions were:")
print(f"Condition 1: {condition1}")
print(f"Condition 2: {condition2}")
# Start the game
guessing_game()
Welcome to the guessing game!
You need to guess if two statements are True or False.
Is the first condition True? (yes/no)
Is the second condition True? (yes/no)
Both conditions were False. You lose!
PYTHON HW HACK 3:
def check_number(number):
if number < 0:
return "The number is negative."
else:
return "The number is not negative."
# Test the function
print(check_number(-10)) # Output: The number is negative.
print(check_number(5)) # Output: The number is not negative.
The number is negative.
The number is not negative.
PYTHON HW HACK 4:
def check_scores(score1, score2):
if score1 >= 70 and score2 >= 70:
return "Both scores are 70 or above."
else:
return "One or both scores are below 70."
# Test the function
print(check_scores(75, 80)) # Output: Both scores are 70 or above.
print(check_scores(60, 80)) # Output: One or both scores are below 70.
Both scores are 70 or above.
One or both scores are below 70.
PYTHON HW HACK 5:
def check_vowel(character):
vowels = "aeiouAEIOU"
if character in vowels:
return f"{character} is a vowel."
else:
return f"{character} is not a vowel."
# Test the function
print(check_vowel('a')) # Output: a is a vowel.
print(check_vowel('B')) # Output: B is not a vowel.
a is a vowel.
B is not a vowel.
Javascript pop Hack 1:
function outfitPicker(temp) {
if (temp <= 32) {
return "It's freezing! Wear a heavy coat, gloves, and a scarf.";
} else if (temp > 32 && temp <= 60) {
return "It's chilly! Wear a jacket and jeans.";
} else if (temp > 60 && temp <= 80) {
return "It's warm! A t-shirt and shorts should be fine.";
} else if (temp > 80) {
return "It's hot! Wear light clothing like a tank top and shorts.";
} else {
return "Please enter a valid temperature.";
}
}
// Example: Prompting the user to input the temperature
let temperature = prompt("Enter the temperature:");
console.log(outfitPicker(Number(temperature)));
Javascript pop Hack 2:
function findLargestAndSort(numbers) {
numbers.sort((a, b) => a - b); // Sorting numbers in ascending order
console.log(`Sorted numbers from least to greatest: ${numbers}`);
console.log(`The largest number is: ${numbers[numbers.length - 1]}`);
}
// Example usage
let numberList = [34, 15, 88, 2, 43, 19];
findLargestAndSort(numberList);
Javascript pop HACK 3:
function checkEvenOrOdd(num) {
if (num % 2 === 0) {
return `${num} is even.`;
} else {
return `${num} is odd.`;
}
}
// Example: Prompting the user to input a number
let number = prompt("Enter a number:");
console.log(checkEvenOrOdd(Number(number)));
JAVASCRIPT HW HACK 1:
function checkPassword(password) {
// Check if the password is at least 10 characters long, includes both uppercase and lowercase letters,
// has at least one number, one special character, no spaces, and no more than 3 consecutive letters.
const hasUppercase = /[A-Z]/.test(password);
const hasLowercase = /[a-z]/.test(password);
const hasNumber = /\d/.test(password);
const hasSpecialChar = /[!@#$%^&*(),.?":{}|<>]/.test(password);
const noSpaces = !/\s/.test(password);
const noMoreThanThreeSameLetters = !/(.)\1{2}/.test(password); // Checks for more than 3 consecutive letters
const isValidLength = password.length >= 10;
// Simplifying using De Morgan’s Law: !(A && B && C && D) becomes !A || !B || !C || !D
if (!isValidLength || !hasUppercase || !hasLowercase || !hasNumber || !hasSpecialChar || !noSpaces || !noMoreThanThreeSameLetters) {
return "Password does not meet the criteria.";
}
return "Password is valid!";
}
// Test the function
console.log(checkPassword("MySecurePass1!")); // Should return "Password is valid!" if it meets all criteria
console.log(checkPassword("badpass")); // Should return "Password does not meet the criteria."
