Assume your assembly language includes ONLY the following instructions: 'inc REG': increments a given register by one. 'dec REG': decrement a given register by one. 'jnz LABEL': jumps to a given LABEL if the previous instruction's result was not zero. 'HALT': stops running. Task: A and B registers hold non-negative values. The program should calculate the value of |A-B| and locate the result in C. In addition, the language holds registers C,D,...,Z, which you can assume are initialized at program start to zero.
