https://leetcode.com/contest/5/problems/binary-watch/ 这个题应该是这次最水的,这个题目就是二进制,然后是10位,最大1024,然后遍历,找二进制里面1的个数为满足要求的,然后判断是否超限,题目说的很清楚,小时0到11,分钟0到59,然后转化成要求的格式就行了. class Solution { public: vector<string> work(int k) { vector<string> res; ) return re…

463. Island Perimeterhttps://leetcode.com/problems/island-perimeter/就是逐一遍历所有的cell,用分离的cell总的的边数减去重叠的边的数目即可.在查找重叠的边的数目的时候有一点小技巧,就是沿着其中两个方向就好,这种题目都有类似的规律,就是可以沿着上三角或者下三角形的方向来做.一刷一次ac,但是还没开始注意codestyle的问题,需要再刷一遍. class Solution { public: int islandPerime…
