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.
Input: 10 2 [and 9 test cases more] Output: 6 4 [and 9 test cases more]
why simple division is giving an error but integer division working fine when I am already subtraction excess apples and then doing division and then converting it to int... I don't see where data loss occur :(
AC after 3 WA solved in cpp using strings, learned a lot. Real programmers would solve using string. mind the case 5555
Don't forget to put -'0' in there. Took one day to figure out.
@shauryauppal thanks man for providing test cases.
This question is just beautiful in so many ways!
Oh my fucking god. Finaly got AC in C++ after 10 hours of debugging. This taught me how to properly take your inputs and manage memory.
If you're wondering, the inputs given will always have valid answers. For example,
If you're using Python 3, do integer division (// operator) , otherwise it will perform floating point division and when casting it to int, there will be data loss resulting in an incorrect result.
In JAVA, use BigInteger and enjoy.
