I need help with this code in assembly. I cannot get my ouput the way the proffesor wants it.

; Similar to Chapter 4 exercises: Sum the difference between each element in an array

; Example: dwordarray dword 1,5,6,9

;Program description here:

; 2/1/2018

; Assembly Language

; You need a loop below to make this program work properly. Since we use dword array as

; our variable size then that means you add what to get to the 4?

; Would it be dwarray[esi+4]?

; Subtract array element that has 1 in it from element that has 5 in it. Then

; put it in a register like edx. You get 4. Next repeat that with element that has 5 from 6.

; add that to the register edx and you get 5. Repeat with array that has 6 in it from element that has 9, then add

; that to edx register with 5 and you get 8 as the total. Now put what is in the

; edx register into the eax register and print.

; remember at the bottom of the loop add 4 to the esi register each time

; to get to the next element in the array.

;####### Student start code using the next 4 lines.###########

dec count ; Start by moving count - 1 into the

mov ecx,0 ; ecx register because an array starts at 0.

mov esi,0 ; move 0 into esi register

mov edx,0 ; Use the edx register to sum each difference so move 0 into it.

L2: ; start loop#### remember--- dwarray is 1,4,5,7

; ########Student only needs 4 steps in the loop.#######

mov eax,dwarray[esi+4] ; First you move the array from above into the eax register by using the

sub eax,dwarray[esi-2] ; arrayname followed by [esi+4]. This is the second element in the array.

add edx,eax ; now subtract the first element from the eax register by using subtract arrayname follow by [esi].

; next add what is in the eax register to a register. suggestion use edx.

add [esi],4 ; next add 4 to the pointer called esi

loop L2 ; End loop####
