I'm working on analysis of various groups of numbers in file.txt
I need to do an analysis of the numbers for things like
- how many times does each number occur
- how many times does each number in each slot
On the most basic level, can someone share advice on how to approach this? I was thinking an array of arrays, or a hash of arrays, but am not clear.
Incidentally, I know a bit about working with arrays but hashes are my achilles heel -- I've gotten them to work a bit before, but no matter how many tutorials I've done on hashes the "aha" moment of truly understanding them eludes me...
