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.

Lesson learnt, don't use python 3.4 for this problem

AC in one go.... Lengthy implementation with c/c++

getting a NZEC runtime error in java ? Can anybody tell the reasons for it ?

AC in one go. learned BigInterger in java. thats all!

ac in one go
only sub and div will suffice

Took me about an hour to implement add/sub/div2 on strings in c... then less than 2 minutes in Haskell

Solved by BigInteger java and c++ string to array method both.

BigInteger was new for me.

Study from the Above line and then solve this problem.

Can be easily solved using python or Java as it is easy to handle big numbers in both languages.

@shauryauppal but still not AC?
