When to use enumerateObjectsUsingBlock vs. for
...he representation for fast enumeration. There is overhead therein. Block-based enumeration allows the collection class to enumerate contents as quickly as the fastest traversal of the native storage format. Likely irrelevant for arrays, but it can be a huge difference for dictionaries.

Assuming you have control over the implementations of the types, you should derive from a common base class or implement a common interface and make the calls on those (you can use the as or is operat...

how to calculate binary search complexity
...urrence relations :
T(N) = aT(N/b) + f(N)
Here, a = 1, b = 2
=> log (a base b) = 1
also, here f(N) = n^c log^k(n) //k = 0 & c = log (a base b)
So, T(N) = O(N^c log^(k+1)N) = O(log(N))
