Is a Java hashmap search really O(1)?
I've seen some interesting claims on SO re Java hashmaps and their O(1) lookup time. Can someone explain why this is so? Unless these hashmaps are vastly different from any of the hashing algorithms I was bought up on, there must always exist a dataset that contains collisions.

How to access command line parameters?
The Rust tutorial does not explain how to take parameters from the command line. fn main() is only shown with an empty parameter list in all examples.

What is the difference between lower bound and tight bound?
...the upper bound, while Omega is the lower bound. Theta requires both Big O and Omega, so that's why it's referred to as a tight bound (it must be both the upper and lower bound).
For example, an algorithm taking Omega(n log n) takes at least n log n time, but has no upper limit. An algorithm taking...
