Question

When an input that has not been completely read reached a state (final or otherwise) that it cannot leave because there is no outgoing edge that it may follow. The input or the machine __________ at that stage.

a)Crashes
b) Fail
c) Accepted

Answer 1

The computational machine 'crashes' when an input cannot be completely read as there is no transition for the current symbol under that state. It signifies an error or unsuccessful processing, unlike an 'accepted' input which indicates successful processing.

Step-by-step explanation:

When an input that has not been completely read reaches a state within a computational machine (such as a finite automaton) and cannot proceed because there is no transition defined for the current symbol under that state, the machine is said to 'crash' at that stage. This term generally indicates an error or an unsuccessful termination of the processing, because the state machine or the automaton is not designed to handle that specific situation. This is different from the input being 'accepted,' which implies that the input has been successfully processed and meets the criteria defined by the machine for acceptance.
