N people, with ID numbers 1, 2, …, N, are lining up in front of a bank. There will be Q events. The following three kinds of events can happen. 1 : The teller calls the person with the smallest ID number who has not been called. 2 x : The person with the ID number x comes to the teller for the first time. (Here, person x has already been called by the teller at least once.) 3 : The teller again calls the person with the smallest ID number who has already been called but has not come. Print the ID numbers of the people called by the teller in events of the third kind翻译

why people say that marriage is the tomb of love, give a speech about 200 words.

Marriage is often seen as the ultimate symbol of commitment and devotion between two individuals, yet why do some people suggest that it is the "tomb of love"? For many, the idea of "marriage" conjures up images of a lifeless, mundane and restrictive existence. Once the initial excitement of falling in love fades, some couples might feel trapped in a cycle of routine and predictability, which can leave their love feeling stagnant and unfulfilling. This is where the cliche of the "tomb of love" comes from - the fear that marriage will somehow stifle and suffocate the passion that once existed between two people.

However, it is important to remember that no relationship, including marriage, is free from challenges or hardships. The key to overcoming these obstacles lies in communication, commitment, and a willingness to work through problems together. Furthermore, marriage can be a fulfilling and rewarding experience, offering opportunities for growth, companionship, and intimacy.

Ultimately, whether marriage becomes a "tomb of love" or a source of fulfillment lies in the hands of the individuals involved. It is up to each partner to choose love, to nurture the relationship, and to maintain the spark that ignited their love in the first place. Rather than fearing the "tomb of love", we should embrace the possibilities and growth that marriage can bring to our lives, learning to cherish and appreciate the person we have committed to spending our lives with.

Write a program that calculates the number of cakes needed for a given number of guests at a party, where each guest receives 1 slice of cake. The program should ask the user to enter the number of people that are attending, and the number of slices in each cake. The program will print the number of cakes needed. Note: You will need to import the math module

Sure! Here's a program that calculates the number of cakes needed for a given number of guests at a party:

import math

def calculate_cakes_needed():
    num_people = int(input("Enter the number of people attending the party: "))
    slices_per_cake = int(input("Enter the number of slices in each cake: "))

    cakes_needed = math.ceil(num_people / slices_per_cake)

    print("Number of cakes needed:", cakes_needed)

calculate_cakes_needed()

In this program, we first import the `math` module to use the `ceil()` function, which rounds up a number to the nearest integer.

Then, we define the `calculate_cakes_needed()` function that asks the user to enter the number of people attending the party and the number of slices in each cake. We convert the user inputs to integers using `int()`.

Next, we calculate the number of cakes needed by dividing the number of people by the number of slices per cake, and rounding up using `math.ceil()`.

Finally, we print the number of cakes needed.

Note that the code assumes that each guest will only have one slice of cake.
