只是做一个过程记录。下面是个人的安装过程。 使用环境 Debian10.1+Maple2019 安装过程 1、从百度网盘下载Maple2019 for linux。再次吐槽百度网盘，不是VIP就没法活。 2、利用unzip解压Maple2019。 3、chmod +x *.run。修改脚本的运行属性。 4、sudo ./Maple2019.0LinuxX64Installer.run。运行安装脚本。我的安装路径是/opt/maple2019。 5、cd crack。跑到crack目录。 6、chmod +x *.pl。修改perl脚本运行属性。 7、sudo ./crack.pl /opt/maple2019。这里我出现了两个错误。 错误修正 Perl模块没有安装 Perl模块没有安装，这个容易解决。 sudo apt install -y perl 这样就可以搞定。 没有lsb模块 是运行crack.pl后，出现 lmutil没有这个文件或者目录 这个问题搞了我很久，明明lmutil可执行文件在对应的目录下，就是没法执行。后面阅读Readme.txt发现，要安装LSB模块。 if the LSB is not installed yet, do it now! 开始我通过sudo apt install -y lsb，Debian告诉我没有lsb这个包。WTF。

（一）二叉树 1. A - Binary Tree Traversals A binary tree is a finite set of vertices that is either empty or consists of a root r and two disjoint binary trees called the left and right subtrees. There are three most important ways in which the vertices of a binary tree can be systematically traversed or ordered. They are preorder, inorder and postorder. Let T be a binary tree with root r and subtrees T1,T2. In a preorder traversal of the vertices of T, we visit the root r followed by visiting the vertices of T1 in preorder, then the vertices of T2 in preorder. In an inorder traversal of the

America's temperate climates produce forests with hundreds of hardwood species -- trees that share certain biological characteristics. Although oak, maple and cherry all are types of hardwood trees, for example, they are different species. Together, all the hardwood species represent 40 percent of the trees in the United States.
