You have been given the opportunity to do some work on the new TISC (two instruction code) microprocessor, which has been designed to execute at lightning speeds.

The processor implements only two instructions:

STO <register>,<address> ( store from this register to this address )
SUB <register>,<address> (subtract the value at this address, from this register)

It also contains only two 32 bit registers: A and B

The machine you’re working on has two 32 bit ram addresses: 0 and 1

When the machine boots up, assume it magically begins executing your code. The value of A and B are unknown. Write a program to copy RAM location 0 into RAM location 1, and then optimize the program to use the fewest number of instructions possible.
