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.

How about solving it from scratch without using C++ Boost library.

the problem becomes very very easy if u use BigIntegers in java ,no trouble of handling long digits .

visit c++ boost library

AC, Learnt something new (java.math.BigInteger)

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 :) :)

Same code

python 2 : AC
python 3 : WA

useless if u do this in python

vurise18: 2019-06-27 11:19:33

how is it that this question is so simple in logic and writing code but still WA in c++??

Java people please learn BigInteger class before attempting this question.Its quite helpful while dealing with large numbers.

what would be a better way to store the string? String objects in cpp or an array of char. (for a general set of problems like big numbers.)
