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 "blue.mary.me@qq.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.
Interactive Protocol
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.
Example
The example of communication.
Input: 3 15 42 Output: 3 15 42
Attention: the program should clear the output buffer after printing each line.
Reference
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 wrote my code in Visual Studio and it worked (gave the output that it wanted)… is there a specific solution??? Like do I need a user's input or just use an array that's already initialized with values. |

Easy one, Read the question carefully, after printing the output you should flush the buffer(https://support.microsoft.com/en-in/help/94227/how-to-flush-the-cout-buffer-in-visual-c) |

isn't the use of fflush is little bit too much for the newbies? |
