Convert the following formula from infix to postfix (Reverse Polish Notation): (A + B * C)/(D + E*F) For part B and C, write code that performs the computation used in problem 1A (A + B * C)/(D + E * F) for using CPUs that have the following instruction formats Three-operand instructions You may only use registers A through F, plus X and T. Registers A through F may not be changed, i.e. their values are fixed. Register T may be used as a temporary register, and Register X must contain the final answer. Stack instructions
