605.202 Data Structures LAB 1 Use of Stacks Assume a Machine has a single register and six instructions (Problem 2.3.10 from the LAT text.) LD A places the operand A in the register ST A places the contents of the register into the variable A AD A adds the contents of the variable A to the register SB A subtracts the contents of the variable A from the register ML A multiples the contents of the register by the variable A DV A divides the contents of the register by the variable A Write a program that accepts a postfix expression containing single letter operands and the operators +, -, *, and / and prints a sequence of instructions to evaluate the expression and leaves the result in the register. Use variables of the form TEMPn as temporary variables. For example, using the postfix expression ABC*+DE-/ should print the following: LD B ML C ST TEMP1 LD A AD TEMP1 ST TEMP2 LD D SB E ST TEMP3 LD TEMP2 DV TEMP3 ST TEMP4 Use the following postfix expressions for input AB+C- ABC+/CBA*+ ABC+- AB-*CBA+-* AB-C+DEF-+$ ABC-/BA-+/ ABCDE-+$*EF*- ABC+$CBA-+* ABC+*CBA-+* AB0+/CBA+-/ Keep in mind that you are NOT evaluating the postfix expression, you are generating the machine language instructions that would perform the evaluation if actually executed. Needs to read an input file and produce output txt file. In java please
