给予一个矩阵,矩阵有1有0,计算每一个1到0需要走几步,只能走上下左右. 解法一: 利用dp,从左上角遍历一遍,再从右下角遍历一遍,dp存储当前位置到0的最短距离. 十分粗心的搞错了col和row,改了半天………… Runtime: 132 ms, faster than 98.88% of C++ online submissions for 01 Matrix. class Solution { public: vector<vector<int>> updateMatrix(…

542. 01 Matrix https://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 . class Solution { public: vector<vector<int>> updateMatrix(vector<vector<int>>& matrix) { ].size…

输入:只包含0,1的矩阵 输出:元素1到达最近0的距离 算法思想:广度优先搜索. 元素为0为可达区域,元素为1为不可达区域,我们的目标是为了从可达区域不断地扩展至不可达区域,在扩展的过程中,也就计算出了这些不可达区域到达最近可达区域的距离. 每个可达元素都记录了到当前位置的距离,因此在后续的遍历中,如果是经由当前节点到达的下一节点,这个距离会被累加. #include <iostream> #include <vector> #include <queue> using…

Given an integer n, generate a square matrix filled with elements from 1 to n2 in spiral order. For example, Given n = 3, You should return the following matrix: [ [ 1, 2, 3 ], [ 8, 9, 4 ], [ 7, 6, 5 ]] 解题思路: 参考Java for LeetCode 054 Spiral Matrix,修改下…
