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 PYTHON3):

Solution:

# A +
# print(int(input()) % 2)

# B
# good = ['cool', 'great', 'not bad', '!']
# for i in range(10):
#     print(i, flush=True)
#     r = input().strip().lower()
#     for g in good:
#         if g in r:
#             print('normal', flush=True)
#             exit(0)
# print('grumpy', flush=True)

# C +
# input()
# a = [int(x) for x in input().split()]
# while a:
#     for i in range(len(a)-1):
#         if abs(a[i] - a[i+1]) >= 2:
#             print('NO')
#             exit(0)
#     a.pop(a.index(max(a)))
# print('YES')

# D
# print(20)

# E +
# n = int(input())
# a, b = 0, 0
# for _ in range(n):
#     _, s = input().split()
#     if s == 'soft':
#         a += 1
#     else:
#         b += 1
# if a < b:
#     a, b = b, a
# x = 0
# for i in range(1, 200):
#     x += 1 + (i*2 - 1) // 4 * 2
#     if a <= x and b <= i**2 - x:

    if dt == 0:
