"crunch"--I@can't understant its meaning!

Your question is technically off-topic here, as it's not a question
about the C language but about an algorithm implemented in C.
Would you consider questions about health care for puppy dogs
(for example) on-topic here, just because someone mentioned it in a
comment in a C program?
But anyway, "crunching" usually means a process of converting data
into other data that takes up less space. How it is implemented in the
Arc program is off-topic here as it is a question about the Arc
algorithm and not about C.
