JULKA - Julka

Julka surprised her teacher at preschool by solving the following riddle:

Klaudia and Natalia have 10 apples together, but Klaudia has two apples more than Natalia. How many apples does each of he girls have?

Julka said without thinking: Klaudia has 6 apples and Natalia 4 apples. The teacher tried to check if Julka's answer wasn't accidental and repeated the riddle every time increasing the numbers. Every time Julka answered correctly. The surprised teacher wanted to continue questioning Julka, but with big numbers she could't solve the riddle fast enough herself. Help the teacher and write a program which will give her the right answers.


Write a program which

  • reads from standard input the number of apples the girls have together and how many more apples Klaudia has,
  • counts the number of apples belonging to Klaudia and the number of apples belonging to Natalia,
  • writes the outcome to standard output


Ten test cases (given one under another, you have to process all!). Every test case consists of two lines. The first line says how many apples both girls have together. The second line says how many more apples Klaudia has. Both numbers are positive integers. It is known that both girls have no more than 10100 (1 and 100 zeros) apples together. As you can see apples can be very small.


For every test case your program should output two lines. The first line should contain the number of apples belonging to Klaudia. The second line should contain the number of apples belonging to Natalia.

using python it is just z = ( x + y ) / 2 print z z = x - z print z after so many WA i use python

take care of leading zeros of the string as ;-
s.erase(0, min(s.find_first_not_of('0'), s.size()-1));
s=> string

Many people have given test cases like 5555 5555 etc. i.e total appled and more apples have same value but how is than even possible.
AC, please don't bother about these kind of test cases.

If you really want to learn something from this question do it in c++ (don't use BigInteger class from java)

A moment of silence for those who used python :P

what should be output for inputs

Use python if you wanna avoid writing your own divide and add functions.

don't forget to use the loop for taking input and displaying output for 10 cases !!
