#Write a Python program that reas a three-digit positive integer. The 
#program separates the input number into it's individual digits and 
#finds the product of its digits. In addition, the program prints the 
#digits in reverse order on separate lines. For example, if the input 
#number was 236 the program will print
#The product is: 36
#6
#3
#2

#Example: Input 236 how we can separate the digits?
#last=236%10
#236//10=23
#middle=23%10=3
#23//10=2
#first=2%10=2

#input
num=int(input("enter integer between 100 and 999 "))

#calculations
last=num%10
num=num//10
middle=num%10
num=num//10
first=num%10
product=last*middle*first

#output
print("product=", product)
print("digits in reverse order")
print(last)
print(middle)
print(first)
