Question

С клавиатуры вводится шестизначное число, определить является ли оно счастливым. Т.е. сумма первых трех цифр равна сумме второй тройки цифр. Если да - вывести `1`, если нет - `0`. (Воспользоваться тем, что `0` делится на любое число).

Answer 1

реализация в python

a = list(map(int, list(input())))

if len(a) == 6:

if sum(a[:3]) == sum(a[3:]):

 print(1)

else:

 print(0)

else:

print("ERROR: length of number != 6")

Answer 2

Problem Statement

You are given a six-digit number entered from the keyboard. You need to determine whether it is a "happy" number. A number is considered "happy" if the sum of the first three digits is equal to the sum of the last three digits. If it is a "happy" number, output `1`; otherwise, output `0`. You can use the fact that `0` is divisible by any number.

Solution

To determine whether a six-digit number is "happy," we need to calculate the sum of the first three digits and the sum of the last three digits. If these two sums are equal, the number is "happy" and we output `1`; otherwise, we output `0`.

Here's the algorithm to solve this problem: 1. Read the six-digit number from the keyboard. 2. Extract the first three digits and the last three digits from the number. 3. Calculate the sum of the first three digits and the sum of the last three digits. 4. If the sums are equal, output `1`; otherwise, output `0`.

Let's implement this algorithm in Python:

number = int(input("Enter a six-digit number: "))

# Extract the first three digits and the last three digits
first_three_digits = number // 1000
last_three_digits = number % 1000

# Calculate the sum of the first three digits and the sum of the last three digits
sum_first_three_digits = first_three_digits // 100 + (first_three_digits // 10) % 10 + first_three_digits % 10
sum_last_three_digits = last_three_digits // 100 + (last_three_digits // 10) % 10 + last_three_digits % 10

# Check if the sums are equal and output the result
if sum_first_three_digits == sum_last_three_digits:
    print(1)
else:
    print(0)

Please note that this solution assumes the input is a valid six-digit number. You may need to add additional input validation if necessary.

Example:

Input: ``` Enter a six-digit number: 123321 ``` Output: ``` 1 ```

Explanation:

In this example, the first three digits are 123, and the last three digits are 321. The sum of the first three digits is 1 + 2 + 3 = 6, and the sum of the last three digits is 3 + 2 + 1 = 6. Since the sums are equal, the number is "happy," and the output is `1`.
