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...

So, does your bridge finding algorithm use only one additional array? In that case it should be faster than the common one, did you measure that? Does it work when parallel edges are allowed? It would be nice to see the actual code to get the answers. → Reply -is-this-fft- 6 ...
DFS (Depth First Search) is an algorithm used to traverse graph or tree. We first select the root node of a tree, or any random node(in case of graph) and explore as far as possible in a branch and then come back to a fixed point. DFS is generally used for connectivity questions....
