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.

@petr_ivashkov can you tell me the output for 1000 and 1?

I did in c what's wrong in the code

Awesome problem for C++ without Boost. Try below test cases: 100 10, 100 100, 999999 99, 99 9, 5555 55, 1000000000000000000000 9999999999999998, 114 6

there's even an invalid input 5 and 2
which answer should be 3 and 2

and if 0 is answer it will leave blank

rohitvish1819: 2021-08-18 21:45:39

For input

the O/p should be

but it will take
500 as valid (Please correct me if I'm wrong)

It took me three fu*cking days to get AC.
but in this comment i wanna give you some hints.
first of all if you are writing python or java , your job is easy!
but getting Ac in c++ without using boost library is little bit tricky!

you should use arrays or vectors. when working with large numbers you can store each digit inside the array.
but the hard part is to write your own adding , subtracting and dividing functions.
by searching the google you can learn how to implement those functions.
good luck
