Problem: In this problem you will write a simple code generator for a 2D programming language derived from [Brainfuck](https://en.wikipedia.org/wiki/Brainfuck).

The code in this language is a rectangular grid of characters '.' and 'X'. The code is converted to a Brainfuck program as follows: the characters are read in the usual order (top to bottom, left to right), and each 'X' character is converted a Brainfuck instruction to be executed. The instruction is defined by the left, top and right neighbors of the 'X' character using the following conversion table:

You are given a string. Output a program in the described language which prints this string.

You can download the language interpreter used for judging here: <https://assets.codeforces.com/rounds/952/puzzling-interpreter.cpp> (use C++11 to compile the code). Note several implementation details:

  * The first step of the language interpretation is conversion to a Brainfuck program, which is then executed.
  * The code must be rectangular, with all lines of the same length. It can have at most 10,000 lines and 10,000 columns, and can have at most 500,000 'X' characters.
  * The code has toroidal topology, i.e. the 'X' on the first line will have top neighbor in the last line.
  * Brainfuck interpreter has 30000 memory cells which store integers from 0 to 255 with increment/decrement done modulo 256.
  * Console input (, command) is allowed in Brainfuck code but has no effect when executed.

Input

The input consists of a single string of characters with ASCII codes between 33 ('!') and 122 ('z'), inclusive. The length of the string is between 1 and 10 characters, inclusive.

Output

Output a program in the described language which, when executed, will print the given message.

Example

Input

$$$

Output

.......X.......
......XXX......
.....XXXXX.....
....XXXXXXX....
...XXXXXXXXX...
..XXXXXXXXXXX..
.XXXXXXXXXXXXX.
...............
X.............X
X..............
X..............
X..............

Note

The example corresponds to the following Brainfuck program:
    
    
           -  
          >+<  
         >+++<  
        >+++++<  
       >+++++++<  
      >+++++++++<  
     >+++++++++++<  
      
    <             >  
    .  
    .  
    .  
    

The triangular block decrements the first memory cell and sets the value of the second memory cell to 36 - the ASCII code of '$' character. The next line after the triangular block moves the memory pointer to the second memory cell, and the next three lines print the '$' character three times.

Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
char arr[100];
vector<char> res[10010];
int row;
void a() {
  res[row].push_back('.');
  res[row + 1].push_back('.');
}
void b() {
  res[row].push_back('.');
  res[row + 1].push_back('X');
}
void c() {
  res[row].push_back('X');
  res[row + 1].push_back('.');
}
void d() {
  res[row].push_back('X');
  res[row + 1].push_back('X');
}
int main() {
  int n, i, j;
  scanf("%s", arr);
  n = strlen(arr);
  for (i = 0; i < n; i++) {
    int t = (int)arr[i];
    row = 3 * i;
    a();
    b();
    for (j = 0; j < t; j++) {
      d();
      b();
    }
    d();
    a();
    d();
    a();
    for (j = 0; j < t; j++) {
      b();
      a();
    }
    d();
    b();
    a();
  }
  int mx = 1;
  for (i = 0; i < 3 * n; i++) mx = max(mx, (int)res[i].size());
  for (i = 0; i < 3 * n; i++) {
    int t = mx - (int)res[i].size();
    for (j = 0; j < t; j++) res[i].push_back('.');
  }
  for (i = 0; i < 3 * n; i++) {
    for (char &t : res[i]) printf("%c", t);
    printf("\n");
  }
  return 0;
