✏️ Your Turn: Analyse These Algorithms

For each algorithm below, run the code, then write the inputs, outputs, and purpose in the text box.

Algorithm A

🐍 Algorithm A

temperatures = [18, 22, 25, 30, 28, 15, 20]
hot_days = 0

for temp in temperatures:
    if temp >= 25:
        hot_days = hot_days + 1

print("Hot days (25+):", hot_days)
print("Total days:", len(temperatures))

Write your analysis for Algorithm A:

📖 Show Model Answer — Algorithm A

Inputs: A list of daily temperatures [18, 22, 25, 30, 28, 15, 20]

Outputs: The number of hot days (3) and total days (7)

Purpose: This algorithm counts how many days had a temperature of 25 degrees or above from a list of daily temperatures, and displays the count alongside the total number of days.

Algorithm B

🐍 Algorithm B

def is_even(number):
    if number % 2 == 0:
        return True
    else:
        return False

values = [4, 7, 10, 3, 8, 1]
even_numbers = []

for val in values:
    if is_even(val):
        even_numbers.append(val)

print("Even numbers:", even_numbers)

Write your analysis for Algorithm B:

📖 Show Model Answer — Algorithm B

Inputs: A list of numbers [4, 7, 10, 3, 8, 1]

Outputs: A list containing only the even numbers [4, 10, 8]

Purpose: This algorithm uses a function to check if each number is even, filters a list to keep only the even numbers, and displays the result. It uses the filter pattern combined with a subprogram.
