It can be used as an entry-level question for STL. I forgot to consider that the last character string should not end with 5, so there is always one less data ..

# Include <string> # include <set> # include <iostream> # include <cstdio> # include <stdlib. h> using namespace STD; int main () {string s; while (CIN> S) {Multiset <int> q; string S1 = ""; for (INT I = 0; I <S. size (); ++ I) {If (s [I] = '5') {If (s1.size () = 0) continue; int A = atoi (s1.data (); q. insert (a); S1 = "";} else S1 + = s [I];} If (s1.size ()> 0) // This point is missing {int A = atoi (s1.data (); q. insert (a);} If (Q. empty () {printf ("0 \ n"); c Ontinue;} Multiset <int>: iterator ITER; For (iter = Q. Begin (); iter! = Q. End (); ++ ITER) printf ("% d", * ITER); printf ("\ n");} return 0 ;}
