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.

1. read exactly 10 cases. had cost me WA.
2. make sure you handle edge cases like 5 5, 55 55, 1000 1, etc.
3. test your solution!

use strings to really understand the concept.Try out these test cases:
1.) 999999
2.) 5555
3.) 2003
4.) 999999

JULKA is like PULKA in python 3 :p

Try doing this without using BigInteger(JAVA) or Boost lib in cpp, only then this problem would benefit you. In case you are solving for learning purposes. You can use BigInteger to cross-check test cases with your own string manipulation code.

Make sure that there are exactly 10 test cases. So don't read the no of test cases. Caused me several WAs

Don't use python3 just for this problem. it won't help you to learn anything.
