    int i,count=0;
    fgets(examCode,30,stdin);
    for(i=0;examCode[i]!='\0';i++){
        if(examCode[i]>='0' && examCode[i]<='9'){
            count++;
        }

public class TutoringGuide{
    public static void main(String args[]){
        Scanner sc = new Scanner(System.in);
        String examCode = sc.nextLine();
        int count = 0;
        for(int i=0;i<examCode.length();i++){
            if(examCode.charAt(i)>='0' && examCode.charAt(i)<='9'){
                count++;
            }
        }
        System.out.print(count);
    }
}

examCode = input()
count = 0
for ch in examCode:
    if ch>='0' and ch<='9':
        count+=1
print(count)
