# Popcorn Hack 1: Prompt the user to enter a number n. Initialize total_sum to 0. Use a loop to iterate from 1 to n. Add each number to total_sum. Print the total_sum. (Python)
# Function to get valid integer input
def integer():
    while True:
        try:
            n = int(input("Enter a number: "))
            return n  # If input is valid, return the number
        except ValueError:
            print("Invalid input. Please enter a valid integer.")

# Get a valid number from the user
n = integer()

# Initialize total_sum to 0
total_sum = 0

# Use a loop to iterate from 1 to n and add each number to total_sum
for i in range(1, n + 1):
    total_sum += i

List of fruits:
apple
banana
cherry
date
Repetition 1: TWhat is your favorite fruit?
Repetition 2: TWhat is your favorite fruit?
Repetition 3: TWhat is your favorite fruit?
Repetition 4: TWhat is your favorite fruit?
Repetition 5: TWhat is your favorite fruit?

// Popcorn Hack 2: Create a function that uses 4 of the 5 basic arithmetic operations and returns the number 32 as the answer. (Javascript)
function calculate32() {
    // Using four arithmetic operations: +, -, *, /
    let result = (8 * 5) - (4 / 2) + 6;  // 8*5 = 40, 4/2 = 2, 40 - 2 + 6 = 44
    result = result - 12;  // Final adjustment to get 32 (44 - 12 = 32)
    return result;
}

// Call the function and log the result
console.log(calculate32());  // Output: 32
