Do all three question:

$1)[10]$ Write an assembly program $($for $32-$bts MASM assembler and uses irvine$32.$inc$)$ with enough

comments that will use five variables having $16-$bit decimal integers and the output will be as

follows: $(2P+R)-(Q-S)-3T$

$2)[10]$ Write an assembly program $($for $32-$bts MASM assembler and uses irvine$32.$inc$)$ that uses a

loop to calculate first twenty values of the Fibonacci number sequence, described by the following

formula: Fib$(1)=1,$ Fib $(2)=1,$ Fib $($n$)=$Fib $($n$-1)+$ Fib $($n$-2).$

$3)[10]$ Write an assembly program $($for $32-$bts MASM assembler and uses irvine$32.$inc$)$ that uses a

loop with indirect or indexed addressing to reverse the element of an integer array. Do not copy the

elements to another array. Use SIZEOF, TYPE, and LENGTHOF operators to make the program

more general and flexible.
