Water King continues

First, the topic requirements

With the development of the Forum, the administrator found that the water king did not, but the statistical results show that there are three posts a lot of ID. According to the statistics of their posts more than 1/4, you can quickly find them from the list of posts?

Second, design ideas

Three people post the number of more than One-fourth, so four a group, are not the same elimination, the last remaining is the three.

Third, design code

1#include <iostream.h>2 intMain ()3 {4     intid[Ten]={1,2,3,4,4,3,2,2,3,4};5     intId_null;//define an ID that does not exist6     intshui[3];7     inta[3];8     inti;9shui[0]=shui[1]=shui[2]=0;Tena[0]=a[1]=a[2]=Id_null; One      for(i=0;i<Ten; i++) A     { -         if(id[i]==a[0]) -         { theshui[0]++; -         } -         Else if(id[i]==a[1]) -         { +shui[1]++; -         } +         Else if(id[i]==a[2]) A         { atshui[2]++; -         } -         Else if(shui[0]==0) -         { -shui[0]=1; -a[0]=Id[i]; in         } -         Else if(shui[1]==0) to         { +shui[1]=1; -a[1]=Id[i]; the         } *         Else if(shui[2]==0) $         {Panax Notoginsengshui[2]=1; -a[2]=Id[i]; the         } +         Else A         { theshui[0]--; +shui[1]--; -shui[2]--; $         } $     } -cout<<"The three water kings were:"<<Endl; -cout<<a[0]<<" "<<a[1]<<" "<<a[2]<<Endl; the     return 0; -}

Iv. results:

V. Summary of the Experiment

Fill the job. The main is to look at the students thinking and code. A few days without programming, rusty ....
