Write a procedure str_str that receives two pointers to strings string and substring via the stack and searches for substring in string. If a match is found,

it returns in EAX the starting position of the first match. Matching should be casesensitive. A negative value is returned in EAX if no match is found. For example,

if

string = Good things come in small packages.

and

substring = in

the procedure should return 8 in EAX, indicating a match of in in things.
