原题传送门 1. 题目描述 2. Solution 1 1、思路分析 DFS. 可以将二维网格看成一个无向图，竖直或水平相邻的1之间有边相连。为了求出岛屿的数量，可以扫描整个二维网格，如果一个位置为1，则以其为起始结点进行深度优先搜索。在深度优先搜索的过程中，每个搜索到的1都会被重新标记为0。 最

Islands and Bridges Description 给定一些岛屿和一些连接岛屿的桥梁，大家都知道汉密尔顿路是访问每个岛屿一次的路线，在我们这个地图中，每个岛屿有个正整数的权值，表示这个岛屿的观赏价值。假设一共有N个岛屿，用Vi表示岛屿Ci的价值，汉密尔顿路C1C2…Cn的价值是以下三部分的总和： (1
给你一个由 '1'（陆地）和 '0'（水）组成的的二维网格，请你计算网格中岛屿的数量。 岛屿总是被水包围，并且每座岛屿只能由水平方向和/或竖直方向上相邻的陆地连接形成。 此外，你可以假设该网格的四条边均被水包围。 来源：力扣（LeetCode） 链接：https://leetcode-cn.com/problems/number-of-isla

1.题目大意 这道题我认为配不上蓝题，我觉得这不科学，这道题的神奇之处在于它的题面描述十分的神奇。 中文翻译可能有一些问题，我们看看英文翻译，它要求我们在去到一个岛后立马回到原来的岛。这不就是一个菊花图吗？？ 2.代码实现 我们先用并查集来把环缩掉，然后直接枚举以每个节点为中心的
