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]

Important Points which to avoid a WA
1. remove the starting 0's
008 is not a valid output, 8 is
2.important test cases (0,0) and (1000,998)
3. make sure the string is bigger than 102 characters(else segmentation fault will occur)

Finally got an AC!!! tips for future learners like me :-
1) you have to learn to debug your program , because this one takes a lot of small hacks
2) try to do it in C/C++ which will teach you the actual difficulty which lies in this problem
#) do not panic if the code goes to about 60-70 lines , i guarantee if it's 60-70 you have written good code :) .

Simple for JAVA use BigInteger
