2. Given the Postfix expression
25∗923 +/−
(a) Evaluate it. Show the sequence of push and pops with their arguments and the state of the stackafter each operation as well as the final result.(b) Write the infix equivalent(c) Write the prefix equivalent3. Assume the existence of a templated classstackwhose implementation is unknown (array versusnodes), with operationspush,popandisEmpty.
3.Assume that andS1is an instance of classstackthatcontains integer elements. Write a booleanstackmethod that takes as a parameter anotherstackS2,and returns true if and only if the elements ofS2are exactly the same as the elements of thestack.Your stacks must not be destroyed at the end of the process.
