Create a simulated MARIE cpu$+$memory that can run the following MARIE assembler instructions:

LOAD X$,$ STORE X

ADD X$,$ SUBT X

SKIPCOND $000.$ SKIPCOND $400,$ SKIPCOND $800$

JUMP X

OUTPUT, INPUT

HALT.

You do not need to create assembler program, you can directly use an array $($e$.$g$.,$ int M$[4096]).$

How?

Allow the OPCODE in an single integer, and the OPERATOR in the next integer.

Consider, for example, we want to write a simple MARIE program to load

the accumlator with X$=12$ and then display it and halt.

M$[0]=$ LOAD, M$[1]=10,//$ load X into AC

M$[2]=$ OUTPUT; $//$ display AC

M$[3]=$ HALT;

$...$

M$[10]=12$; $//$ X $=12$
