The code is as follows:

#include <iostream>#include<cstdio>using namespacestd;intMain () {ints;  while(SCANF ("%d", &s) &&s) {intf=0, t=0, M; T cannot be defined outside the loop body, otherwise the results of the previous group of cases will be added while(s>2) {f+=s/3; M=f-T; S=m+s%3; T=F; }        if(s==2) F++; printf ("%d\n", F); }    return 0;}

Variable definition location must be more attention!!!!

Write the question is very slag, Theseus do not have self-esteem, but female man still want to persist. There is nothing in the world to cure flat, but there are accidents in fact. If you come, you must conquer!
