foreach my $key (keys %data) {
print "$key=$data{$key}\n";
}解释一下这段代码
:
这段代码使用 Perl 语言从一个文件中读取数据到一个 hash 中,然后打印出 hash 中的数据。首先使用
open
函数打开文件,然后使用chomp
函数去掉文件中每一行末尾的换行符,再使用split
函数将每一行按照等号=
分割成 key 和 value,最后将 key 和 value 赋值到 hash 中,最后使用foreach
循环打印出 hash 中的数据。 -

用C加加实现一个函数Clear,这个函数参数是一个指针,指向一个类型为node的二叉树节点(node类型有三个值,分别代表着这指向左子树,右子树的指针和节点本身的值,当没有左子树和右子树时,指针指向null),这个函数可以将参数及其子树的值全部设为零,该函数不得出现异常
,即使参数指向null也要正常运行。
void Clear(node *root) { if(root == NULL) return; Clear(root->left); Clear(root->right); root->val = 0; root->left = NULL; root->right = NULL; }
