distance ah? But don't forget, we enumerate in order, that is, the furthest point on the lower boundary is bound to be enumerated and updated at that point. What is the difference between this algorithm and ①? Its complexity is n*m, which is obviously suitable for this method when the diagram is small.Code:#include #include #include #include #define N 1010using namespace STD;intL,w;intH[n][n];intLe[n][n];intRi[n][n];int MapN [N];Chars[2];intMain () {scanf("%d%d", l,w); for(intI=1; i for(intj=1;

Maximum sub-matrix ... Suspension Line Method: Time complexity O (nm) http://blog.csdn.net/wzq_qwq/article/details/47167707The method of suspension is to record the maximum length of an h extension (hanging line), L, R to the left to the right to extend the maximum length, and then by recursion to get.------------------------------------------------------------------#include using namespace std;#define OK (c) ((c) = = ' F ' | | (c) = = ' R ')const int MAXN = 1009; int H[MAXN][MAXN], L[MAXN][MAX

information in a distributed computing environment. 　Part Four: Configuration file I learned the configuration file when I was learning design patterns, so it was kind of nice to see this chapter. reviewed the page configuration settings, application settings. Also learned the customerrors settings. The convenience of a configuration file is that it is stored in plain text format, written in XML, and requires no server restart if changes are required.Iv.
