The union process in the deterministic finite automata (DFA) is explained below −If L1 and If L2 are two regular languages, their union L1 U L2 will also be regular.For example, L1 = {an | n > O} and L2 = {bn | n > O}L3 = L1 U L2 ... Read More

ProblemShift the input string right by one place and design a Turing Machine (TM) that can perform right shift over ∑ = {0, 1}.SolutionRefer an algorithm given below to design a TM −Step 1 − Move right side to the last character from the initial character.Step 2 − If the character ... Read More

Turing’s machine is more powerful than both finite automata and pushdown automata. These machines are as powerful as any computer we have ever built.Formal Definition of Turing MachineA Turing machine can be formally described as seven tuples(Q, X, Σ, δ, q0, B, F)Where, Q is a finite set of states.X ...
