Write pseudo-code, not Java, for problems requiring code 1. Write a prefix method to accept an infix string and create the prefix form of that string, assuming that the string is read from right to left and that the prefix string is created from right to left. Handle variables, +-1/,+,$, (,). Design and implement a stack in which each item on the stack is a varying number of integers. Choose a Java data structure to implement your stack and design push and pop methods for it, without using library functions. Hint: Make it as simple as possible
