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.


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


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.


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.

cost me 2 WA since i was thaking user input for no. of test cases

abhi14598: 2016-12-12 18:39:53

do i have to store all output and print in the end or just print it after each input??

=(Francky)=> As you want, both can give AC.

what about the cases like:
I mean what I want to ask is, do I have to take 0.5 into consideration as well? Or am I supposed to distribute whole apple??

bunnycoder test cases are working perfectly for me. But still I am getting wrong answer in C++?
Any ideas why? Or any more test cases?

Those of u getting wa in python3 is because python3 cant handle the input!!! If you input 10^30 it will treat the following as string and if you convert that stuff into integer using int function. It will convert that value into the range of integer thus you're getting wa. And dats not the same with python2.7 :) :)

Thanks to such a silly reading mistake -_- . It costed me two wrong answers and my streak of 8 got broken -_-
