正文之前

好久没弄C++了，上学期颓废了半学期，这学期开学就搞课程设计快疯了。待会要考试CSP，所以弄点代码储备，待会到了考场说不定能省点功夫！

正文

#include <iostream>
#include<queue>
#define Max 1000

using namespace std;
struct Graph
{
   int  a[10][10];
};


bool visited[10];
queue<int> path;
int width=0;

void BFS(Graph tu,int start)
{
    visited[start]=true;
    path.push(start);
    while(path.size()!=0)
    {
        int top=path.front();
        path.pop();
        visited[top]=true;
        cout<<top<<endl;
        for(int i=0;i<10;++i)
        {
            if(tu.a[top][i]!=Max && visited[i]==false)
            {
                visited[i]=true;
                path.push(i);
            }
        }

    }
}

int main()
{
    Graph tu;
    for(auto &s:tu.a)
        for(auto &x:s)
            x=Max;
    int a,b;
    for(auto &s:visited)
        s=false;
    for(int i=0;i<8;++i)
    {
        cin>>a>>b;
        tu.a[a][b]=tu.a[b][a]=1;
    }
    BFS(tu,1);
}
