我觉得这题目有问题,我的程序一点没错,就是通不过,题错了!!!!!!!#include<iostream.h> int fn( int**, int, int); void print(int**,int,int); void main() { int p,t; cin>>p>>t; //int *a=new int[p];//总的树木; int **arr=new int *[p]; for(int i=0;i<p;i++) arr[i]=new int [102]; int j; for(i=0;i<p;i++) for(j=0;j<102;j++) arr[i][j]=0; int pp,tt,z=0; while(cin>>pp>>tt) { z++; arr[pp-1][tt-1]=1; arr[pp-1][t+1]=1; } //print(arr,p,t); if(z!=0){ int total=fn(arr,p,t); // print(arr,p,t); cout<<total<<endl; } else cout<<0<<endl; } int fn(int **arr,int p,int t) { int pp=1,i=0,j,k,q=0; for(i=0;i<p;i++) if(arr[i][t+1]==1) for(j=i+1;j<p;j++) if(arr[j][t]==0&&arr[j][t+1]==1) { for(k=0;k<t;k++){ if(arr[i][k]!=arr[j][k]) { pp++; //cout<<"pp="<<pp<<" i="<<i<<" j="<<j<<endl; break; } else q++; } if(q==t) {arr[j][t]=1;}//cout<<"arr["<<j<<"]"<<endl;} q=0; } return pp ; } void print(int **arr,int p,int t) { for(int i=0;i<p;i++) { for(int j=0;j<t+2;j++) cout<<arr[i][j]<<' '; cout<<endl; } } Followed by:
