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.


[and 9 test cases more]

Author of problem was too lazy to completely write input...

For those wondering how to solve this in c++ without using string manipulation.
Use boost library in c++
visit this link for more clarification on how to use

don't forget about test-cases guys, costed me 1WA :) and try to implement it using array/string instead of big integer library or boost

Fiitjee rocks. you cant clear jee useless

Check the case 103 103 and 108 108

Don't worry about an odd-even combination as input. It's not said that we can cut an apple so it's against the logic. (result would be a fraction)
Remember to implement big numbers - one may get WA because of it.

finally AC in cpp
