#Shortest

leetcode 542. 01 Matrix 、663. Walls and Gates(lintcode) 、773. Sliding Puzzle 、803. Shortest Distance from All Buildings

542.01Matrixhttps://www.cnblogs.com/grandyang/p/6602288.html将所有的1置为INT_MAX,然后用所有的0去更新原本位置为1的值。最短距离肯定使用bfs。每次更新了值的地方还要再加入队列中。classSolution{public:vector<vecto...

581. Shortest Unsorted Continuous Subarray

begin,end必须初始化,如果整个数组是排序好的,经过for循环后,begin、end还是原始的值。注意:end必须比begin小1,因为最终的长度是end-begin+1,关键在于这个+1的地方 classSolution{public:intfindUnsortedSubarray(vector<...

最短路径遍历所有的节点 Shortest Path Visiting All Nodes

2018-10-0622:04:38问题描述:问题求解:对于边没有权重的最短路径的求解,首选的方案是bfs。本题要求是求遍历所有节点的最短路径,由于本题中是没有要求一个节点只能访问一次的,也就是说可以访问一个节点多次,但是如果表征两次节点状态呢?可以使用(curNode,VisitedNode)来进行表征,如果两次的已...
