- How would you design a stack which, in addition to push and pop, also has a function min which returns the minimum element? Push, pop and min should all operate in O(1) time. Your design (in pseudo code) should include a class Stack and three functions, i.e., push, pop, and min.arrow_forwardUsing the PEP 8 machine. Create a function that takes 2 arguments and returns a result. When I say function I mean that the parameters and the return value are passed on the stack . You code must have a function and a main program that calls the function using the stack. Assignment will not be accepted if you are not passing parameters and return value in the stack. Please note a complete "pass by stack" example is below. The function adds two numbers. Feel free to use that as starter code. The function you do should be one of three operations: 1) multiply - return the product of the two factors 2) divide - return the quotient ( integer arithmetic ) 3) remainder / modulo - return the remainder of the division of the two factors.arrow_forward5. fast please Convert the following infix expression into its prefix and postfix equivalents: a / b - (c + d * e) / f * g For any postfix, show the final transformed expression using the stack method for transformation as explained in class showing all the relevant steps. For the prefix, show any needed reversion and the final transformed expression using the stack method for transformation as explained in class showing all the relevant steps. Draw and sequence your diagrams clearlyarrow_forward
