WebMay 23, 2024 · Non-deterministic Finite Automata (NFA) : NFA is a finite automaton where for some cases when a single input is given to a single state, the machine goes to more than 1 states, i.e. some of the moves cannot be uniquely determined by the present state and the present input symbol. An NFA can be represented as M = { Q, ∑, ∂, q0, F}. Q → Finite … WebMar 25, 2024 · The cardinal number or the cardinality of the set A is 5. Types of Sets –. (i) Singleton Set –. A set consisting of only one element is said to be Singleton set. For example : Set S = {5} , M = {a} are said to be singleton since they are consists of only one element 5 and ‘a’ respectively.
