Unique Paths
问题：从起点到终点总共有多少条路径 分析：f[x,y]=f[x+1,y]+f[x,y+1]，用记忆化搜索就可以解决了 class Solution { public: int num[110][110]; int dfs(int m,int n,int x,int y) { if(num[x][y]) return num[x][y]; if(x==m-1 && y==n-1) return 1; if(x+1<m) num[x][y]

Header Search Paths 与 User Header Search Paths 的区别
在解决cocoaPods导入第三方类import不提示头文件名称的过程中，发现build settings中有Header Search Paths和User Header Search Paths User Header Search Paths还有一个对应的设置，Always Search User Paths，但已被废弃。 先看Header Search Paths。 Header Search Paths Header Search Paths是用于存放项目中头文件的搜索根源，没有add到项目里的头文件，可以通过该配置引入，例如cocoaPods导入的三方类 <>是只会从Header Search Paths中搜索（在使用cocoaPods过程中，默认会将pods下的三方类头文件加入至Header Search Paths，所以import三方类时，需要注意要使用
