Question

Python. Пожалуйста, сделайте за курс 10 класса!!! Мудрённые для десятиклассника элементы Python не используйте, пожалуйста. ————————————————————————Определить сколько существует «счастливых» автобусных билетов в одной серии с номерами от 000000 до 999999. «Счастливым» считается билет, сумма первых трех цифр которого равна сумме вторых трех цифр.​

Answer 1

happy_nums = 0

for i in range(1000000):  # от 100000 до 1000000 не включительно.

   n2 = i % 1000  # Вторые три цифры

   n1 = i // 1000  # Первые три цифры

   

   sum2 = 0

   while n2:

       sum2 += n2 % 10

       n2 //= 10

   sum1 = 0

   while n1:

       sum1 += n1 % 10

       n1 //= 10

   if sum1 == sum2: happy_nums += 1

print(happy_nums)  # 50412

Answer 2

Counting "Happy" Bus Tickets

To determine the number of "happy" bus tickets in a series with numbers ranging from 000000 to 999999, we need to find the tickets where the sum of the first three digits is equal to the sum of the last three digits.

To solve this problem, we can use a simple loop to iterate through all possible ticket numbers and check if they meet the given condition. Since you mentioned that we should avoid using complex elements of Python, we will stick to basic programming concepts.

Here's a Python code snippet that solves this problem:

count = 0

for ticket in range(0, 1000000):
    # Convert the ticket number to a string and pad it with leading zeros if necessary
    ticket_str = str(ticket).zfill(6)
    
    # Extract the first three digits and the last three digits
    first_three = int(ticket_str[0]) + int(ticket_str[1]) + int(ticket_str[2])
    last_three = int(ticket_str[3]) + int(ticket_str[4]) + int(ticket_str[5])
    
    # Check if the sum of the first three digits is equal to the sum of the last three digits
    if first_three == last_three:
        count += 1

print("The number of 'happy' bus tickets in the series is:", count)

This code initializes a variable `count` to keep track of the number of "happy" bus tickets. It then iterates through all ticket numbers from 000000 to 999999. For each ticket number, it converts it to a string and pads it with leading zeros if necessary. It then extracts the first three digits and the last three digits and checks if their sums are equal. If they are, it increments the `count` variable.

Finally, it prints the total count of "happy" bus tickets in the series.

Please note that this code may take some time to execute since it checks all possible ticket numbers. However, it provides a straightforward solution to the problem without using any complex Python elements.
