Description
In order to become familiar with the virtual machine and its assembly language, you have to write an assembly code that performs a comparison.
The machine is initialized with two random values in the registers R5 and R6.
At the end of the program, R0 must contain 1 if the values are different, 0 otherwise.
The bytecode will be sent in hexadecimal format, which can be generated using the provided assembler (assembly.py file).
The documentation of the virtual machine is available on this page.
