Amazing challenge! This challenge made me understand what buffer overflows are

Excellent beginner exercise! I had heard of buffer overflow so many times but never really got into understanding what is it all about. Now I had a better understanding. Wasted hours looking at the YouTube videos of Live Overflow and did not know what to do with the nc hint at all! Also wasted time trying to compile the source code! Then, suddenly, I realised I had to use the netcat tool and enter the command as given in the hint in my Kali Linux VM. Then I just play around and observe how different lengths of input string changes the memory. One trick: the way the code reads the bytes is opposite from the way to override the bytes.
should have been worth at least 20 points not easy at all!
Really liked the challenge.

This was excellent!! Love the display showing how the characters are overwritten in memory! Thanks for the great learning chal!
