In Nasm:

In the following code what it's needed to sort the array in ascending order:

;;;;;;;;;;;;;;;;;;;; MACRO DEFINITIONS ;;;;;;;;;;;;;;;;;;;;

; A macro with two parameters

; Implements the write system call

%macro writestring 2

mov eax, 4 ;sys_write system call number

mov ebx, 1 ;file descriptor std_out

mov ecx, %1 ;message to write from parameter 1

mov edx, %2 ;message length from parameter 2

int 0x80

%endmacro

;;;;;;;;;;;;;;;;;;;; DATA SEGMENT ;;;;;;;;;;;;;;;;;;;;

section .data

msg1 db 'Before sorting: '

lenmsg1 equ $-msg1

msg2 db 'After sorting: '

lenmsg2 equ $-msg2

asciinums db '7','3','2','1','0','5','6','4','8','9'

lenasciinums equ $-asciinums

crlf db 0x0d, 0x0a

lencrlf equ $ - crlf

section .text

global _start

_start:

writestring msg1, lenmsg1

writestring asciinums, lenasciinums

writestring crlf, lencrlf

;fill in missing lines of code here

writestring msg2, lenmsg2

writestring asciinums, lenasciinums

writestring crlf, lencrlf

mov eax, 1 ;terminate program
