为什么老是WA?求给组测试数据!(Code)#include <iostream.h> #include <stdlib.h> #include <math.h> /* int cmp ( const void *a , const void *b ) { return *(int *)a - *(int *)b; } */ void doRun() { int i,j,k,l,n; long *a,temp; bool flag; while(cin>>n) { if(n == 0) return; a = new long[n]; for(i=0;i<n;i++) { cin>>a[i]; } //qsort(a,n,sizeof(a[0]),cmp); for(i=0;i<n-1;i++) { for(j=i+1;j<n;j++) { if(a[i]>a[j]) { temp=a[i]; a[i]=a[j]; a[j]=temp; } } } flag = false; temp = a[n-1]; for(i=n-1;i>=3;i--) { for(j=0;j<i;j++) { for(k=j+1;k<i;k++) { for(l=k+1;l<i;l++) { if(a[i] == a[j]+a[k]+a[l]) { flag = true; temp = a[i]; goto loop; } } } } } loop: if(flag) cout<<temp<<endl; else cout<<"no solution"<<endl; } } int main() { doRun(); return 0; } Followed by: Post your reply here: |
