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 10100 (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]

Code in C++ after Python to compare. This problem is much more complex in C++. Well worth doing both.

Trivial using Python 3 (no limit to integer number size). Choose the right tool for the job.

This is time taking if you do without using any libraries , spent 4 hrs building from scratch i dont think it was worth it:(

AC in one go,
due to big integers i made function for basic calculation using string XD , which consisted of bugs and i fixed them during making them.

You can also test your code against the following test cases.
299 101
100 100
100 0
0 0
10000000 9999998
100 14

AC after 8WA's

guys pls keep the size of the array >102 got 2 WA's coz of the same, rest you can see previous comments for more guidance, great community!!

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
99
2.) 5555
5555
3.) 2003
65
4.) 999999
