# To check the correctness and complexity of our prefix-or implementations we introduce two helper functions. Function `correctness(pf)` tests a given prefix-or function on a range of inputs. Function `complexity(pf, n)` determines the or-complexity and or-depth of `pf` for input lists of length `n`.
