刚才弄错了，这才是第二个源码，可以实现输入一二叉树的前序与中序，输出其后序-have just made a mistake, this is the second source, can achieve an input sequence of binary tree with the sequence, then the output sequence

SELECT `a`.`aid`,`a`.`title`,`a`.`create_time`,`m`.`username` FROM `jrk_downrecords` `a` INNER JOIN `jrk_member` `m` ON `a`.`uid`=`m`.`id` WHERE `a`.`status` = 1 GROUP BY `a`.`aid` ORDER BY `a`.`create_time` DESC LIMIT 10 [ RunTime:0.091450s ]
