; This Procedure search a given item in a given array

; Receives: EBX, ESI, ECX, EDX content as input.

; EBX contains the item we want to search on the array

; ESI contains the address of the first item in the array

; ECX contains the number of items in the array

; EDX contains the size of each item in the array

; Returns : EAX,

; If the item found in the array, EAX stores the item we are searching

; Otherwise, EAX contains $-1$

; Requires: Nothing

retWrite a function that search an item in the array

The $.$data section contains two items $-$ "array" and "sample"

You have to write a procedure that search "sample" in the "array".

If the item is found return the item using EAX register, otherwise, return $-1$ using

EAX register.

You can pass the parameters using registers

Push the register arguments at the beginning of the procedure. And pop them

at the end of the procedure.
