Challenge Overview
Currently in algo contests, the output is compared by exact match. If it matches the reference answer exactly, test is passed, otherwise it is failed. One exception is made for double return values, but still comparison procedure is fixed (min{absolute error, relative error} must be <= 1e-9).
For most problems this is enough and this is convenient. However, sometimes we want to have more complicated ways to compare competitors output and the reference answer.
This contest is going to seeking ways to support custom output checker.
