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]

	ivar: 2013-07-27 07:13:32 @all:when the sum of two i/p is odd as in 20 and 7...,keep the second o/p one less than the result...ie for this case o/p should be 13 and 6 (not 13 and 7) Last edit: 2013-07-27 07:14:05
	teja: 2013-07-13 12:44:02 I used strings to do computations.In case of test cases mentioned by @Daniel, I am appending appropriate ".5" at the end.My logic is correct but i am getting WA.Can any one think of where the problem could be? Last edit: 2013-07-13 12:46:42
	Prakhar Gupta: 2013-07-08 08:24:18 pls help...my code work fine in ideone.. but here giving WA <snip> Last edit: 2022-07-04 23:32:27

	[Lakshman]: 2013-05-12 18:30:15 @Parshant garg No data type can handle it, You can use Python or Java Biginteger instead of c/c++, In c you need to built your own container.. Last edit: 2013-05-12 18:30:46
	Parshant garg: 2013-05-09 12:18:46 how to achieve 10^100.... is it long long int work?
	robot: 2013-05-08 18:38:41 @Jay check this: http://docs.python.org/3.0/whatsnew/3.0.html#print-is-a-function
	Daniel: 2013-03-29 15:05:26 I don't get this! Let the test cases be as 10 // No of Apples 3(or any odd no.) // Extra Apples Klaudia has What would be the result? Also consider the following 11 // Total no of apples 2(or any even number)// Extra apple Klaudia has What would be the outcome? I think there is no answer for this Please help
