Using different graph storage structure adjacency matrix, adjacency table respectively Dfs, I think I am lonely, should try and check set, see can use and check set of DFS,BFS instead of ... Scared and checked.Adjacency Matrix DFS #include #include using namespace std; const int maxn=1001; Int G[MAXN][MAXN]; int n,tmp; BOOL VIS[MAXN]; void Dfs (int v) { Vis[v]=true; for (int i=1;i { if (!vis[i]g[v][i]>0) DFS (i); } } int Dfstra () { int i; Fill (vis,vis+maxn,false); int cnt=0; for

And to check the connectivity of the set judgment.#include #include#include#include#include#includeusing namespacestd;Const intmaxn=1010;structedge{intU,v;} E[MAXN*MAXN];intn,m,k;intF[MAXN];intFind (intx) { if(X!=f[x])returnf[x]=Find (f[x]); returnf[x];}intMain () {scanf ("%d%d%d",n,m,k); for(intI=1; i) scanf ("%d%d",e[i].u,e[i].v); for(intI=1; i) { intId scanf"%d",ID); intsz=n-1; for(intj=1; jJ; for(intj=1; j) { if(E[j].u==id)Continue; if(E[j].v==id)Continue;

The first step, first modify the relevant JS fileOpen/js/shopping_flow.js FileRemove the following JS code if (frm.elements[' province ') frm.elements[' province '].value = = 0 frm.elements[' province ']. Length > 1){Err = true;Msg.push (Province_not_null);} if (frm.elements[' city ') frm.elements[' city '].value = = 0 frm.elements[' City '].length > 1) { err = true; Msg.push (city_not_null); } if (frm.elements[' district ') frm.elements[' district '
