Introduction to Graph with Breadth First Search(BFS) and Depth First Search(DFS)graph based search engine
是这样的,刚开始看到关键词-“找最短转换序列”,瞬间想到用BFS求最短路径去做,但在做的过程中发现用队列BFS方法似乎没办法轻松的求深度,也就是这个最短路径到底是多短,后来尝试了记录每一层的进队列出队列数去计算深度,写是写出来了,无奈运行第30个测试用例的时候超出时长限制,我太难了... 踩了几个坑,对...
Given a 2d grid map of'1's (land) and'0's (water), count the number of islands. An island is surrounded by water and is formed by connecting adjacent lands horizontally or vertically. You may assume all four edges of the grid are all surrounded by water. Example 1: Input: 11110 11...

虽然dfs/bfs这类题我是不太建议应届生或者刚入行的小朋友倾注过多的精力去刷的,一般来说,DFS这类问题相当于同学刷题进入了“深水区”。但是最近我看保offer班的同学的战报,发现题目难度直线上升,我决定还是多写一些相对复杂的题目。 我们建了一个微信群讨论群,我们在群里会分享一些 leetcode 的高效刷题方法和面...
