Consider the following code segment. x = u - t; y = x * v; x = y + w; y = t - z; y = x * y;The minimum number of total variables required to convert the above code segment to static single assignment form is Note : This question was asked as Numerical AnswerType.

Automata theory (also known as Theory Of Computation) is a theoretical branch of Computer Science and Mathematics, which mainly deals with the logic of computation with respect to simple machines, referred to as automata. Automata* enables scientists to understand how machines compute the functions and solve problems.
Theory of Computation is very important in compiler design as it helps in writing efficient algorithms, which help make efficient compiler construcion.
