Chinese characters of Empress Wu, or the Zetian characters (), are Chinese characters introduced by Empress Wu Zetian, the only reigning female in the history of China, to demonstrate her power.
 The characters were not created by the Empress herself, but were suggested by an official named Zong Qinke, the son of one of her cousins, in December 689 AD.
 The number of characters varies between 12, 17, 19, or 30 characters.
 They were forcibly used by people during her reign but fell into disuse immediately after her death, so they help to determine dates of printed materials.
Runtime verification is a computing system analysis and execution approach based on extracting information from a running system and using it to detect and possibly react to observed behaviors satisfying or violating certain properties.
 Some very particular properties, such as datarace and deadlock freedom, are typically desired to be satisfied by all systems and may be best implemented algorithmically.
 Other properties can be more conveniently captured as formal specifications.
 Runtime verification specifications are typically expressed in trace predicate formalisms, such as finite state machines, regular expressions, context-free patterns, linear temporal logics, etc., or extensions of these.
 This allows for a less adhoc approach than normal testing.
 However, any mechanism for monitoring an executing system is considered runtime verification, including verifying against test oracles and reference implementations .
 When formal requirements specifications are provided, monitors are synthesized from them and infused within the system by means of instrumentation.
 Runtime verification can be used for many purposes, such as security or safety policy monitoring, debugging, testing, verification, validation, profiling, fault protection, behavior modification (e.g., recovery), etc.
 Runtime verification avoids the complexity of traditional formal verification techniques, such as model checking and theorem proving, by analyzing only one or a few execution traces and by working directly with the actual system, thus scaling up relatively well and giving more confidence in the results of the analysis (because it avoids the tedious and error-prone step of formally modelling the system), at the expense of less coverage.
 Moreover, through its reflective capabilities runtime verification can be made an integral part of the target system, monitoring and guiding its execution during deployment.

The rule of three is a writing principle that suggests that events or characters introduced in threes are more humorous, satisfying, or effective in execution of the story and engaging the reader.
 The reader or audience of this form of text is also thereby more likely to remember the information conveyed.
 This is because having three entities combines both brevity and rhythm with having the smallest amount of information to create a pattern.
 It makes the author or speaker appear knowledgeable while being both simple and catchy.

Question: What is the writing principle that suggests that events or characters introduced in threes are more humorous, satisfying, or effective in execution of the story and engaging the reader and is used in a novel featuring Allison Gross, a hideous witch?
Answer: rule of three
