Detailed explanation-1: -/, (the Kleene closure of L), For a . v/ar language L (a language of the form L = L*, for a given Lx ), call roof of L the smallest language Lņ such that L = L¿ .
Detailed explanation-2: -L∗, the Kleene Closure of L: set of strings formed by taking any number of strings (possibly none) from L, possibly with repetitions and concatenating all of them.
Detailed explanation-3: -A Kleene star, in the parlance of computer science, is a programming resource that offers outcomes related to the concatenation of a string set. Using the Kleene star, developers and others assess how to filter given results based on input. A Kleene star is also known as a Kleene operator or Kleene closure.
Detailed explanation-4: -The closure of a language L is denoted L∗ and represents the set of those strings that can be formed by taking any number of strings from L, possibly with repetitions (i.e., the same string may be selected more than once) and concatenating all of them.
Detailed explanation-5: -Kleene Closure/Kleene Star: It is denoted by ∑*
