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]

@burnwalvishal 100 7 is not a valid input. Don't worry about it. |

Finally Accepted ! Some points to keep in mind - 1. Both numbers can be same (odd or even). 2. Both numbers can be even. 3. Both numbers can be odd. 4. One odd and the other number even is not a valid input, so don't worry about such a case. 5. 0 will not be an input, since question says both inputs are positive integers. All the best ! Great question indeed. |

Do we have to consider the case when answer is in fractions? |

Please limit this problem to languages not supporting big integers. Otherwise, there's no point. Also, increase the numbers of digits to 10000 and re evaluate, otherwise everybody is getting 0.00. It simply makes the problem less challenging. Feeling good after doing it in C/C++ within 3 hours and getting AC on first try. :) |

Use BigInteger for Java. It gets very simple |
