EXPECT - Life, the Universe, and Everything (Interactive)
Note for Interactive problem setters: if you are stucked on how to write a interactive problem judge, you may send a mail to "email@example.com". It will send you the custom judge of this problem.
Your program is to use the brute-force approach in order to find the Answer to Life, the Universe, and Everything. More precisely... rewrite small numbers from input to output. Stop processing input after reading in the number 42. All numbers at input are integers of one or two digits.
You should communicate with Judge using standard input and output.
Attention: the program should clear the output buffer after printing each line.It can be done using fflush(stdout) command or by setting the proper type of buffering at the beginning of the execution - setlinebuf(stdout).
Each time the judge will give you a number. You should rewrite this number to standard output. If this number equals 42, after rewriting your program should terminate immediately.
The example of communication.
Input: 3 15 42 Output: 3 15 42
Attention: the program should clear the output buffer after printing each line.
Please pay attention that: your program should NOT output any extra characters like "J","P" or “:". Follow the interactive protocol strictly. A sample program (in C++) that can get Accepted is as the following:
I didn't understand that question.
can anyone give solution, please
This question is not understandable.
Is there any 'fflushing' in pyhton 3.x ??
how to test
question is not understandable..
What is fflush

In C++ cout << flush; orcout.flush() can be used to flush the buffer.
not sure why the source code is given as reference?
