3. Consider the following language: L = {w€ {a,b}* | 2#a(w) # 3#b(w)}, where #c(w) denotes the number of symbol c occurring in the string w. Construct a pushdown automaton accepting the language L (no conversion from context-free grammar to pushdown automaton is accepted); give brief and precise interpretation of the states and transitions of your machine.

Intelligent Machines

Machines that use artificial intelligence to learn from the environment and past experiences to perform better in the presence of variability and uncertainty are called intelligent machines. Intelligence develops according to environment and experience. It is human-like behavior. When the computer system or any programmed machine learns from the inputs and corresponding outputs, it can be called an intelligent machine.
