    return -1

    #These "asserts" using only for self-checking and not necessary for auto-testing
    assert safe_code("-5#*-1=5#") == 0
    assert safe_code("##*##=302#") == 5
    assert safe_code("19--45=5#") == -1

case safe_code("11+##=11") the answer should be -1 not 0. (the answer cannot consist of zeros (00, 000, etc.).)

Fails on: <pre class='brush: python'>assert safe_code("#*11=#") == 0 assert safe_code("-9-#2=-11") == -1 </pre>
