Question

9. Составьте программы в Python. 1) Найдите произведение цифр четырехзначного числа. 2) Найдите сумму второй, третьей и четвертой цифр пятизначного числа

Answer 1

1) a = int(input())

b = a % 10

c = a % 100 // 10

d = a // 100 % 10

e = a // 1000

print(b * c * d * e)

2) a = int(input())

b = a % 100 // 10

c = a // 100 % 10

d = a // 1000 % 10

print(b + c + d)

Answer 2

I can help you with writing Python programs. Here are some possible solutions for your tasks:

1) To find the product of the digits of a four-digit number, you can use the following code:

# Input a four-digit number as a string
number = input("Enter a four-digit number: ")

# Initialize the product as 1
product = 1

# Loop through each digit and multiply it with the product
for digit in number:
  product = product * int(digit)

# Print the product
print("The product of the digits is", product)

2) To find the sum of the second, third and fourth digits of a five-digit number, you can use the following code:

# Input a five-digit number as a string
number = input("Enter a five-digit number: ")

# Extract the second, third and fourth digits using slicing
digits = number[1:4]

# Initialize the sum as 0
sum = 0

# Loop through each digit and add it to the sum
for digit in digits:
  sum = sum + int(digit)

# Print the sum
print("The sum of the second, third and fourth digits is", sum)
