#Write a Python program that prompts the user to 
#three-digit positive integer number. 
#The program separates the input number into it's individual 
#digits and prints the digits on separate lines. For example if the input 
#number was 236 the program will print 
#2 
#3 
#6 


#three-digit positive integer - is a number between 100 and 999
#the program must separate digits

#Example: 
#input 256 = (2*100+5*10+6)%10 = 6 
#256 dollars and something cost 10 dollars
#how many items can you buy? 25 items 256//10 = 25
#how much money left? 6 256 %10 = 6
#we are using decimal system - base 10
#we need to continue with 25
#25//10=2 25%10=5
#we need to continue with 2
#2//10 = 0 2%10=2
#we separated all digits using integer division and modulo 10 operations

#input 679 = (6*100+7*10+9)
#679 dollars and something cost 10 dollars
#how many items can you buy? 67 679//10 = 67
#how much money left? 9 679%10 = 9
 

#Example: input 378
#to separate digits we will use integer division by 10 
#and modulo (remainder) 10 
#last_digit=378%108
#378//10=37
#mid_digit=37%10=7
#37//10=3
#first_digit=3%10=3

#Discussion: 
#Input: one three-digit positive integer, the number between 100 and 999
#stored in variable num
#Output: digits printed on different lines, we will store individual digits
#in variables first_digit, mid_digit and last_digit
#Input Limitations: integer between 100 and 999 inclusive.
#Calculations: integer divisio by 10 and modulo 10

#Part 1 Input:

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

#Part 2 Calculation:

last_digit = num%10
num = num//10
mid_digit = num%10
num = num//10
first_digit = num%10

#Part 3 Output:
print(first_digit)
print(mid_digit)
print(last_digit)
