Leetcode-training 1)Reverse String A function that reverses a string. The input string is given as an array of characters char[]. Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory. You may assume all the charac...
就是指向函数的指针。 回调函数,表示了一个函数的地址,将函数作为参数进行使用。参考百度百科:http://baike.baidu.com/view/414773.htm 常用的大概就是在sort函数中了吧。 回调函数就是一个通过函数指针调用的函数。如果你把函数的指针(地址)作为参数传递给另一个函数,当这个指针被用来调用其所指向的函数时,我们...

一般化的二叉查找树(binary search tree) “矮胖”,内部(非叶子)节点可以拥有可变数量的子节点(数量范围预先定义好)应用大部分文件系统、数据库系统都采用B树、B+树作为索引结构 区别B+树中只有叶子节点会带有指向记录的指针(ROWID),而B树则所有节点都带有,在内部节点出现的索引项不会再出现在叶子节点中。 B+树...
