Assume a machine that has a single register and six instructions.
LD A Places the operand A into 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 Multiplies the contents of the register by the variable A
DV A Divides the contents of the register by the variable A
Write a java program utilizing stacks that accepts a postfix expression containing single-letter operands and the operators +, -, *, and / and prints a sequence of instructions to evaluate the expression and leave 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 to the console:
LD B
ML C
ST TEMP1
LD A
AD TEMP1
ST TEMP2
LD D
SB E
ST TEMP3
LD TEMP2
DV TEMP3
ST TEMP4
