# C++

#include <cstdio>
#include <cstring>
int main() {
    char a[111];
    scanf("%s",a);
    printf("%d\n",strlen(a));
    return 0;
}

#include <cstdio>
char s[111];
int main() {
    scanf("%s",s);
    int len = 0;
    for (int i=0; s[i]; i++) {
        len += 1;
    }
    printf("%d\n",len);
}

#include <iostream>
#include <string>
using namespace std;
int main() {
    string s;
    cin >> s;
    cout << s.size() << '\n';
    return 0;
}

# Java

import java.util.*;

    public static void main(String args[]) {
        Scanner sc = new Scanner(System.in);
        String s = sc.nextLine();
