1.寻找最短路径BFS可以用于寻找两个节点之间的最短路径。它首先探索起点的所有相邻节点,然后逐层向外扩...
4. 代码理解图 理解: (1)首先设置了(r, c)=(0, 0)作为起始点,也就是数字为1的位置,接下来,我们要想它能往那里走呢?常识告诉我们,它只有(右,下)两条路可以走,那么看看代码,它满足 check 添加 R 和 D 的条件,所以确实和我们想的 一样。 (2)如果check不为空,那么就可以随机选择一个方向走,我们1...
Sudoku is a very simple task. A square table with 9 rows and 9 columns is divided to 9 smaller squares 3x3 as shown on the Figure. In some of the cells are written decimal digits from 1 to 9. The other cells are empty. The goal is to fill the empty cells with decimal digits from...
在leetcode的题中经常要使用DFS深度优先遍历来求解问题,做得多了就会发现这也是有套路的,我这里总结两个套路,以及对应的输出: 代码如下: #include <iostream> #include <vector> #include <map> #include <set> #include <queue> #include <stack> #include <string> #include <climits> #include <algorithm>...

In this tutorial, you will learn about Depth First Search in C with the algorithm and program examples. Most graph problems involve the traversal of a graph. Traversal of a graph means visiting each node and visiting exactly once. There are two types of
计算出key(文件)的hash值hash_code group_index = hash_code % group_count new_hash_code = hash_code高16位和低16位互换 server_index = new_hash_code % 组内 server_count 为啥计算server_index和group_index时使用了不同的hash code? 因为如果group_count和组内server_count相等,例如都等于2,那么对于...
