Apply sorting

Sort prices with bubble sort.

Print the result

Now we add print_sorted(prices). It prints each sorted price on its own line.

This function calls sort_prices and prints the result with a for loop. This visualizes the sorting result.

Printing with a for loop

A for loop is used to print the sorted array. Each element is passed to the print function in order.

This approach makes each sorted price appear on its own line. The output is clean and readable.

Exercise Print result

Write print_sorted(prices). Sort and print each price on its own line. Call print_sorted(init_prices()) to print 12, 23, 45, 67, 99.

Show example solution

def init_prices():
    # Return price array
    return [99, 45, 12, 67, 23]
def sort_prices(prices):
    # Sort
    n = len(prices)
    for i in range(n - 1):
        min_idx = i
        for j in range(i + 1, n):
            if prices[j] < prices[min_idx]:
                min_idx = j
        prices[i], prices[min_idx] = prices[min_idx], prices[i]
    return prices
def print_sorted(prices):
    # Sort and print
    sorted_prices = sort_prices(prices)
    for p in sorted_prices:
        print(p)
print_sorted(init_prices())
