Expanding elements in a list

Hi, I'm looking for a "nice" way to process a list where some elements need to be expanded into more elements (only once, no expansion on the results). Standard iterative way would be to do: i=0 while i < len(l): if needs_expanding(l[i]): new_is = expand(l[i]) l[i:i] = new_is i += len(new_is) else: i += 1 ...

Can you encode to less bits when you don't need to preserve order?

Say you have a List of 32-bit Integers and the same collection of 32-bit Integers in a Multiset (a set that allows duplicate members) Since Sets don't preserve order but List do, does this mean we can encode a Multiset in less bits than the List? If so how would you encode the Multiset? If this is true what other examples are there wh...

FIFO list (moving elements) [C++]

Good evening, people! I'm trying to solve a rather simple problem, but.. well, it seems that I can't. :) The idea is that I have a FIFO list (FIFO queue) with n elements and it's given a value, k (k < n). My little program has to move the elements to the left with k elements. (e.g. for n=4, k=3, a[]=(1, 2, 3, 4), the result is 4 1 2 3)...
