#include <bits/stdc++.h>
using namespace std;
typedef unsigned long long ull;
typedef long long ll;
#define REP(i,x) for(ll i=0;i<(ll)(x);i++)

int main()
{
    ios::sync_with_stdio(false);
    string S;
    cin >> S;
    for(auto it=S.begin(); it!= S.end(); it++)
    {
        *it = 'x';
    }

    cout << S << endl;
    return 0;
