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.
Task
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
Input
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 10^{100} (1 and 100 zeros) apples together. As you can see apples can be very small.
Output
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.
Example
Input: 10 2 [and 9 test cases more] Output: 6 4 [and 9 test cases more]

AC in one go. Dont give up.

Try this test case 1000000000000000000000 9999999999999998 if you're getting WA.

Is it always 10 test cases (20 lines of input always) in the inputs?

After so many iterations finally solved the problem in c++ using string manipulation. Check the test case like 5555 5555 ie when after subtraction the number goes to zero.Another edge case 5555 5553 etc. Last edit: 20191217 15:33:24

Don't use boost library in C++. Good question to practice string manipulation.

Forgot to take care that there are exactly 10 test cases. Phew finally AC.

these sort of questions should be avoided.

Python 3  use // instead of /

Python3 feels like a cheat for this problem... Big integers are handled automatically...

How about solving it from scratch without using C++ Boost library.
