There are a total two questions and you have 2 hours to attempt them.

Do read both the questions before attempting.

Try not to spend all your time trying to solve one question. Please bear in the mind that your calculated value for both programs should be in rax register.

Youve probably heard of factorial of a number. The factorial of the number 6 is 1x2x3x4x5x6 or 6x5x4x3x2x1. In this problem we are going to change is method slightly to our need. In odd factorial, we would multiply just the odd numbers. For example, the odd factorial of 5 would be 1x3x5. Odd factorial of 6 would be 1x3x5 too. Write an assembly program to calculate the odd factorial of a given number stored in a Data Section variable [var1] and store the final value it into rax.

Use double-word multiplication statement for this problem. Below is a template you can use to write your code

; template program

EXIT_SUCCESS equ 0

SYS_exit equ 60

var1 dd 7 ; odd factorial to be calculated

section .text

global _start

_start:

mov rcx, dword [var1] ;

_bye:

mov rax, SYS_exit

mov rdi, EXIT_SUCCESS
