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 AX the starting position of the first match. Matching should be case sensitive. A negative value is returned in AX is no match is found.
For example, if
string = Good things come in small packages
and
substring = in
the procedure should return 8 in AX indicating a match of in in things.
