How to find first element of array which satisfies the given predicate?
I'm asking because I wonder how to implement it efficiently. An array could be very long, say a billion elements, and chances are the first element satisfying a certain predicate may almost certainly be found in first, say, ten elements. This is not about a specific problem, rather I bump into this question every once in a while.
