#include <cstdio>
#include <cstring>
#include <cstdlib>

using namespace std;

char line[82];
char space[82];

int main() {
    scanf("%s", line);
    int len = strlen(line);
    int side_size = (len + 2) / 3 - 1;
    int last_size = len - side_size * 2;
    int space_size= last_size - 2;

    for (int i=0; i<space_size; i++) {
        space[i] = ' ';
    }
    
    const char* p = line;
    const char* q = line + len - 1;
    for (int i=0; i<side_size; i++) {
        printf("%c%s%c
", *p++, space, *q--);
    }
    for (int i=0; i<last_size; i++) {
        printf("%c", *p++);
    }
