while(head>=0)
                cout<<char(stack[head--]+'A'-1)<<stack[head--];
            cout<<endl;

            while(head>=0)
                {
                cout<<char(stack[head]+'A'-1);
                head--;
                cout<<stack[head];
                head--;
                }

我觉得没有区别啊,但是前者是WA,后者却是AC.
