Question

determine if the language is regular, context-free, Turing-decidable, or undecidable. For languages that are regular, give a DFA that accepts the language, a regular expression that generates the language, and a maximal list of strings that are pairwise distinguishable with respect to the language. For languages that are context-free but not regular, prove that the language is not regular and either give a context- free grammar that generates the language or a pushdown automaton that accepts the language. You need not prove that your CFG or PDA is correct. For languages that arc Turing-decidable but not context-free, prove that the language is not context-free and describe a Turing machine that decides the language. You need not describe the Turing machine at the level of states and transitions, but be clear about how the machine operates, and if you use a variant of a Turing machine then justify using that variant. You need not prove that your Turing machine is correct. For languages that are not Turing-decidable, prove the language is not Turing-decidable. {wk1 Wk2 wkn | n ge 0 ^ k ge 2 ^ w1, , wn epsilon {a, b, c}} (so aabbaacc and aaabbbbbbccc arc both in the language because the first is made up of blocks of 2 repeated characters and the second is made up of blocks of 3 repeated characters, but aaabb is not because not all the blocks arc of the same size).

Explanation / Answer

Regular Languages->

A language is called regular on the basis of the idea by that it can decide that a given word is related to a language or is it connected with an algos or any machine language. And also that the word is a special symbol that resides in the computer
