There exists a staircase with N steps, and you can climb up either 1 or 2 steps at a time. Given N, write a function that returns the number of unique ways you can climb the staircase. The order of the steps matters.
For example, if N is 4, then there are 5 unique ways:
1, 1, 1, 1
2, 1, 1
1, 2,...

I'm not a 'cryptographic' anything, so if this is a super-dumb question please let me know (politely).
So here's the deal, say I don't want to store passwords because that opens me up to all sorts of failures (see: Facebook). Instead, I want to use the passwords as a key for something else.

I need to determine the status of a parent object based on 2 variables of each of its children. I came up with a working solution, but this includes a nested "if-else if-else". Needless to say, it doesn't look very elegant.
I was wondering if there is a way to simplify this. I have muddled arou...
