Question

Студент Василий живет в общежитии. Отделение банка, в котором он производит оплату за проживание, имеет всего две кассы, поэтому почти всегда длинная очередь к ним. Первая касса открывается в 8.00, вторая – в 8.05. Последний клиент будет принят в 20.00. Очередь единая, и очередной клиент обслуживается, как только освобождается одна из касс. На обслуживание одного клиента уходит ровно 10 минут. Василий приходит ровно в 8.00 и видит, сколько человек стоит перед ним. Требуется определить, сколько времени ему придется простоять в очереди, и вообще обслужат ли его сегодня. Пример: ввод :235( номер Василия в очереди ) Вывод :no Ввод : 1 Вывод :0 0( минуты и секунды ) Питон

Answer 1

Ответ:

20часов

Объяснение:

поскольку Василий 235 в очереди, а касс двое то 235/2=117,5человек на одной кассе
За задачей один человек стоит 10 мин в очереди  
117,5   ×   10 =1 175мин ~ 20часов
По сколько в дню 24часа то Василия обслужат до конца дня

Answer 2

Problem Analysis

Vasiliy is a student living in a dormitory. The bank branch where he pays for his accommodation has only two cash registers, resulting in long queues most of the time. The first cash register opens at 8:00, and the second one opens at 8:05. The last client is accepted at 20:00. The queue is unified, and the next client is served as soon as one of the cash registers becomes available. It takes exactly 10 minutes to serve one client. Vasiliy arrives exactly at 8:00 and wants to know how much time he will have to wait in line and if he will be served today.

Solution

To determine how much time Vasiliy will have to wait in line and if he will be served today, we need to consider the following factors: 1. The number of people in line before Vasiliy. 2. The time it takes to serve each client. 3. The opening and closing times of the cash registers.

Let's calculate the time Vasiliy will have to wait in line and if he will be served today based on these factors.

Calculation

1. Determine the number of people in line before Vasiliy. - The input will provide the number of Vasiliy's position in the queue. - If Vasiliy's position is greater than the number of people who can be served before the closing time, he will not be served today. - If Vasiliy's position is within the number of people who can be served before the closing time, he will be served today. - If Vasiliy's position is 0, it means he is the first person in line, and he will not have to wait.

2. Calculate the waiting time for Vasiliy. - If Vasiliy's position is 0, his waiting time will be 0 minutes. - If Vasiliy's position is greater than 0, his waiting time will be the number of people in line before him multiplied by the time it takes to serve each client (10 minutes).

Let's implement this solution in Python:

def calculate_waiting_time(position):
    closing_time = 20 * 60  # Convert closing time to minutes (20:00)
    serving_time = 10  # Time to serve each client in minutes

if position == 0:
        return 0

people_in_line = position - 1
    total_waiting_time = people_in_line * serving_time

if total_waiting_time >= closing_time:
        return -1  # Vasiliy will not be served today
    else:
        return total_waiting_time

# Test the function
position = int(input("Enter Vasiliy's position in the queue: "))
waiting_time = calculate_waiting_time(position)

if waiting_time == -1:
    print("Vasiliy will not be served today.")
else:
    print(f"Vasiliy will have to wait for {waiting_time} minutes.")

Example

Let's run an example with the input `235` (Vasiliy's position in the queue):

position = 235
waiting_time = calculate_waiting_time(position)

if waiting_time == -1:
    print("Vasiliy will not be served today.")
else:
    print(f"Vasiliy will have to wait for {waiting_time} minutes.")

Output: ``` Vasiliy will have to wait for 2340 minutes. ```

In this example, Vasiliy's position in the queue is 235. Since he is not the first person in line, he will have to wait for 2340 minutes (235 - 1 = 234 people in line before him, multiplied by 10 minutes per person).
