Sample Input

dog ogdaycat atcaypig igpayfroot ootfrayloops oopslayatcayittenkayoopslay

Sample Output

In my opinion, it is a dictionary tree. However, if I see this question when I search for a binary topic, this question will certainly be solved in binary mode.
I think it's a good idea to use sscanf functions.
 
#include 
  
   #include 
   
    #include using namespace std;struct node{    char s1[20],s2[20];} a[100005];int len;int cmp(node a,node b){    return strcmp(a.s2,b.s2)<0;}int main(){    len = 0;    int i,j;    char str[50];    while(gets(str))    {        if(str[0] == '\0')        break;        sscanf(str,"%s%s",a[len].s1,a[len].s2);        len++;    }    sort(a,a+len,cmp);    while(gets(str))    {        int l = 0,r= len-1,mid,flag = 1;        while(l<=r)        {            int mid = (l+r)>>1;            if(strcmp(str,a[mid].s2)==0)            {                printf("%s\n",a[mid].s1);                flag = 0;                break;            }            else if(strcmp(str,a[mid].s2)<0)                r = mid-1;            else                l = mid+1;        }        if(flag)            printf("eh\n");    }    return 0;}
