Consider this grammar for generating strings of balanced parenthesis:   S -> (S) | SS | () | ^   Where ^ is the empty string with no characters. So, the derivation S => (S) => () is a valid derivation as the S in the (S) in the middle is replaced by nothing. Show two different leftmost derivation trees that generates the string ()(())

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.
