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 plusses[][31] = {
    "..............................", "..............X...............",
    ".............XXX..............", "............XXXXX.............",
    "...........XXXXXXX............", "..........XXXXXXXXX...........",
    ".........XXXXXXXXXXX..........", "........XXXXXXXXXXXXX.........",
    ".......XXXXXXXXXXXXXXX........", "......XXXXXXXXXXXXXXXXX.......",
    ".....XXXXXXXXXXXXXXXXXXX......", "....XXXXXXXXXXXXXXXXXXXXX.....",
    "...XXXXXXXXXXXXXXXXXXXXXXX....", "..XXXXXXXXXXXXXXXXXXXXXXXXX...",
};
int v[] = {0, -1, 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23};
void to_zero(int t) {
  int j = 0;
  while (t) {
    printf("X.");
    j += 2;
    if (j >= 30) {
      j = 0;
      printf("\n%s\n", plusses[0]);
    }
    t--;
  }
  if (j == 0) return;
  while (j > 0) {
    printf("..");
    j += 2;
    if (j >= 30) j = 0;
  }
  printf("\n%s\n", plusses[0]);
}
void printchar(int c) {
  to_zero(c);
  printf("%s\n%s\n%s\n", plusses[1], plusses[1], plusses[0]);
}
int main() {
  int c;
  int last = 256;
  while (true) {
    c = getchar();
    if (c < 33 || c > 122) break;
    int t = last - c - 1;
    if (t < 0) t += 256;
    printchar(t);
    last = c;
  }
  return 0;
