`#include<stdio.h>#include<string.h>main(){int te;int number;int i,j;char a[1000][100];int count[1000];scanf("%d",&number);getchar();while(number!=0){for(i=0;i<1000;i++)count[i]=0;for(te=0;te<number;te++){   scanf("%s",&a[te]);}for(i=0;i<number;i++)for(j=i+1;j<number;j++)if(strcmp(a[i],a[j])==0&&a[j][0]!='*'&&a[i][0]!='*'){ count[i]++;   a[j][0]='*';}for(i=0;i<number;i++){ if(a[i][0]!='*'){  for(j=0;a[i][j]!='\0';j++)     printf("%c",a[i][j]);   printf(" %d\n",count[i]+1);}}           printf("\n");scanf("%d",&number);getchar();}}`
