public class Main {

    public static void main(String[] args) {
        
        Scanner sc=new Scanner(System.in);
        
        int times=Integer.parseInt(sc.nextLine());
        
        while(times-->0){
            
            String s=sc.nextLine();
            StringBuilder sb=new StringBuilder(s.length()*2);
            int ans=0; int continuout=1;
            for(int i=0;i<s.length();i++){
                char c=s.charAt(i);
                if(c=='O'){
                    sb.append(continuout);
                    ans+=continuout++;
                }else{
                    continuout=1;
                    sb.append("0");
                }
                if(i!=s.length()-1) sb.append("+");
            }
            System.out.printf("%s=%d\n",sb.toString(),ans);
        }
