There are at least six different types of complexity in an Ecological community. These types are spacial, structural, temporal, behavioral, geometric and process. Ecologist use these patterns to identify self organizing and emergent phenomena.

The simplest and slowest searching method; the only possible method when the data is unsorted and/or only sequential access is possible (eq. processing a tape file).

I think he's looking for time complexity which I believe is just n

the compexity of linear search in worst case is f(n) = n+1

time complexity is 2^57..and space complexity is 2^(n+1).

A sentence with the word complexity is this sentence doesn't have much complexity.
