JULKA - Julka

#big-numbers

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]

	bhargav0611: 2019-06-29 18:50:52 useless if u do this in python
	vurise18: 2019-06-27 11:19:33 how is it that this question is so simple in logic and writing code but still WA in c++??
	sapto1998: 2019-06-26 14:59:58 Java people please learn BigInteger class before attempting this question.Its quite helpful while dealing with large numbers.
	colar: 2019-06-16 08:28:49 what would be a better way to store the string? String objects in cpp or an array of char. (for a general set of problems like big numbers.) TIA Last edit: 2019-06-16 08:29:23
	jojo9910: 2019-06-01 02:53:43 https://www.geeksforgeeks.org/advanced-c-boost-library/........just read this article Last edit: 2019-06-01 02:54:21
	excel_223: 2019-05-30 23:34:50 using python it is just z = ( x + y ) / 2 print z z = x - z print z after so many WA i use python
	ambuj2512: 2019-05-20 11:29:36 take care of leading zeros of the string as ;- s.erase(0, min(s.find_first_not_of('0'), s.size()-1)); s=> string
	sarthak_1998: 2019-05-18 22:49:06 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. Last edit: 2019-05-18 22:54:55
	i_master: 2019-05-11 05:38:11 OMG LOL, I got 3 WA's because I forgot to remove my human friendly logs from stdout...
	juilee: 2019-05-10 11:23:26 If you really want to learn something from this question do it in c++ (don't use BigInteger class from java)
