    for i in range(n - k + 1):

        for j in range(i, i + k):
            if claim[j] == 0:
                current_tokens += tokens[j]

        if current_tokens > max_tokens:
            max_tokens = current_tokens
            start_index = i

    # Calculate the total tokens and find the item(s) to buy
    total_tokens = 0
    available_items = {}

    for i in range(start_index, start_index + k):
        if claim[i] == 0:
            total_tokens += tokens[i]

    for item in items:
        if item.cost <= total_tokens:
            available_items[item.name] = item.cost

    # Find the minimal wastage and lexicographically smallest item(s)
    minimal_wastage = total_tokens
    for item in items:
        if item.name in available_items:
            wastage = total_tokens - available_items[item.name]
            if wastage < minimal_wastage:
                minimal_wastage = wastage
                result = [item.name]
            elif wastage == minimal_wastage:
                result.append(item.name)

    return result

if __name__ == "__main__":
    n = int(input())
    tokens = list(map(int, input().split()))
    claim = list(map(int, input().split()))
    k = int(input())
    
    items_input = input()
    items_data = items_input.split(": ")
    items = [Item(items_data[i], int(items_data[i + 1])) for i in range(0, len(items_data), 2)]

    result = get_items_to_buy(n, tokens, claim, k, items)

    for item in result:
        print(item)

The code defines a class called Item with two attributes: name and cost.

The get_items_to_buy function takes in several inputs and returns a list of items to buy based on certain conditions.

It first finds the starting index for a "bumper offer" by iterating over a range and checking the tokens and claim values.

Next, it calculates the total tokens and creates a dictionary of available items based on the cost.

Then, it finds the minimal wastage and lexicographically smallest item(s) by iterating over the items and comparing the wastage value.

Finally, it returns the result, which is a list of item names.

The code also includes an if statement to check if the code is being run as the main program, and if so, it takes input from the user and calls the get_items_to_buy function.
