Write the function strend(s ,t) , which returns 1 if the string t occurs at the end of the string s, and zero otherwise.

/*strend: return 1 if string t occurs at the end of s */
int strend(char *s, char *t){
    char *bs = s;   /*remember beginning of strs */
   char *bt = t;

   for(; *s; s++)  /*end of the string s */
         ;
  for(;*t; t++)   /*end of the string t */
         ;
  for(; *s == *t; s--, t--)
      if(t == bt || s == bs)
           break;   /* at the beginning of a str */
  if(*s == *t && t == bt && *s != '\0')
         return 1;
  else
       return 0;
}
