-  My research team has toiled away to create a state-of-the-art neutron collider (Mark Demolisher V - MD5, for short).
-  Can you get two neutrons to collide?

-hints:
-  - We need to execute a certain type of a md5 hash collision attack.
-  - Look for a tool to pull off a "md5 same prefix hash collision" attack.
-  - Use [HashClash](https://github.com/cr-marcstevens/hashclash)
