我为解析文本文件而编写的野牛语法给了我 10 个移位/减少冲突。parser.output 文件对我的帮助不够。该文件给我的信息如下：
State 38 conflicts: 5 shift/reduce
State 40 conflicts: 4 shift/reduce
State 46 conflicts: 1 shift/reduce

我的语法的等效部分是：
statement : word

printf("WORD\n");
$$=$1;
}
|statement word
{
printf("STATEMENTS\n");
$$=$1;
printf("STATEMENT VALUE== %s\n\n",$$);
}
;

{
printf("IDENTIFIER\n");
$$=$1;
}
