rogram prompts for user input $($two characters$)$: $$ user enters $5,$ which is echoed to console $($followed by a newline$)$ and copied to a register. $$ user enters $7,$ which is echoed to console $($followed by a newline$)$ and copied to a different register. $$ Program outputs the text $5-7=($this will actually require at least $4$ distinct output steps using OUT and PUTS$)$ Program converts $5($ascii code$)$ into $5($number$)$ and stores it back in the same register. $$ Program converts $7$ into $7$ and stores it back in the same register. $$ Program takes $2\text{'}$s complement of $7,$ and stores the result back into the same register. $$ Program adds the contents of the two registers $-$ i$.$e$.$ it performs the operation $(5-7)$ and stores the result $(-2)$ in a third register. $$ Program recognizes that the result is negative, obtains the magnitude of $-2(=2),$ and outputs $\text{'}-\text{'}($minus sign$).$ Program converts $2($number$)$ into $\text{'}2\text{'}($ascii code$),$ and stores it back in the same register. $$ Program outputs $\text{'}2\text{'}$ followed by a ne
