迷宫的例子实在太蠢了,我们来看一道大名鼎鼎的Word Ladder.我本人在面Ziillow Onsite时候碰到了原题分享一下我的代码(30行 击败97%的C++solution哈哈): intladderLength(stringbeginWord,stringendWord,vector<string>&wordDict){unordered_set<string>word_dict_;for(auto&word:wordDict)word_dict_.insert(word);if...
DFS BFS都可以做,需要注意的是以门为起点去向下延伸,而不是以房间开始 classSolution{publicvoidwallsAndGates(int[][]rooms){Queue<int[]>queue=newLinkedList<>();for(inti=0;i<rooms.length;i++){// push gate into queuefor(intj=0;j<rooms[i].length;j++){if(rooms[i][j]==0){queue.offer(...
因为每次当seeyou买了可乐以后,阿牛就要求和seeyou一起分享这一瓶可乐,而且一定要喝的和seeyou一样多。但seeyou的手中只有两个杯子,它们的容量分别是N 毫升和M 毫升 可乐的体积为S (S<101)毫升 (正好装满一瓶) ,它们三个之间可以相互倒可乐 (都是没有刻度的,且 S==N+M,101>S>0,N>0,M>0) 。聪明...
You need return the node with the same label as the input node. How we represent an undirected graph:http://www.lintcode.com/help/graph/ Example Example1 Input: {1,2,4#2,1,4#4,1,2} Output: {1,2,4#2,1,4#4,1,2} Explanation: 1---2 \ | \ | \ | \ | 4 Nodes are se...

where the only legal operation is to exchange 'x' with one of the tiles with which it shares an edge. As an example, the following sequence of moves solves a slightly scrambled puzzle: 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 5 6 7 8 5 6 7 8 5 6 7 8 5 6 7 8 9 x 10...
