вернуться в форумMy AC program gives wrong answer on test
4C
1
(C(C))2
formulas are equal, but my program doesn't agree with me. <formula> ::= <sequence> // <sequence>
<sequence> ::= <element><number> // <element><number>
<number> ::= 2 // <element>2
<element> ::= '(' <sequence> ')' // (<sequence>)2
<sequence> ::= <element><element> // (<element><element>)2
<element> ::= C // (C<element>)2
<element> ::= '(' <sequence> ')' // (C(<sequence>))2
<sequence> ::= C // (C(C))2
Without some obvious steps.
Am I wrong? |
