给一个完全二叉树,将当前节点的next值指向其右边的节点。 而在II中则是提供了一个不完全的二叉树,其它需求没有发生改变。 额外的需求包括O(1)的空间复杂度 思路和代码 这里其实是水平遍历(level traversal)的一种实现。我们需要使用一个变量来存储父节点,再使用一个变量来存储当前操作行的,将前一个指针指向当前...

LeetCode 116.populating-next-right-pointers-in-eac 题意 给定一个完美二叉树,其所有叶子节点都在同一层,每个父节点都有两个子节点。二叉树定义如下: struct Node { int val; Node *left; Node *right; Node *next; } 填充它的每个 next 指针,让这个指针指向其下一个右侧节点。如果找不到下一个右侧节点...
Before we learn pointers, let's learn about addresses in C programming. Address in C If you have a variable var in your program, &var will give you its address in the memory. We have used address numerous times while using the scanf() function. scanf("%d", &var); Here, the value ...
