okay but it's kind of weird that almost all accounts on leaderboard are bots. We need to report them. This is a homework helping app not an app for bots, there are so many bots, it's sad, if you see them, report their answer!!! ​

Yes it is horribly irritating, I always report and post a comment saying that its a bot and the file sohuld not be opened. It would be nice if found a way to prevent them. :(

Explanation:

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
