		StringBuilder data = new StringBuilder();
		
		while(true){
			int x = sc.nextInt();  //x?????´??°????????\?????????
			if(x == 0) break;      
			int amariS = 0, syou = x ;  // amariS??????????????????????¨???§???syou???????????§?????????????????§???
	//?¨????????????????????????????
			while(syou > 0) {
				amariS += syou%10;
				syou = syou/10;
			}
			data.append(amariS).append("\n");  //?????£??????????????????????????????????????????????????????syou?????????????????£??????????????????????????????
		}
   //??????
		System.out.println(data);
		
		sc.close();
