# Undecimal

Undecimal is a language invented by User:None1 and it is inspired by Duocentehexaquinquagesimal, which is inspired by Golunar, which is inspired by Unary. It is the same as Duocentehexaquinquagesimal, however it is represented in base-11, in which a space represents ten.

## Examples

### One Time Cat

We have the brainfuck program: `,.`.

We convert it to a number: `110` (`1101100` in binary).

Then we convert the number to base-11: ` 0`, that's it! The one time cat program in this language is ` 0`

```395 6
```

### Hello World

```39506475 9533058 25786 7 27053602440831326587489371 1 999115475
```

### Kolakoski sequence

```

## Implementation

A compiler to brainfuck is in Python:

```def undecimal2num(x):
a='0123456789 '
r=0
for i in x:
if i in a:
r=r*11+a.index(i)
return r
def num2bf(x):
return ''.join(map(lambda a:'><+-.,[]'[int(a)],'{:o}'.format(x)))
def undecimal2bf(x):
return num2bf(undecimal2num(x))[1:]

print(undecimal2bf(input()))
```

## Generator

A translator from brainfuck is also in Python:

```def bf2num(x):
r=1
for i in x:
if i in '><+-.,[]':
r=r*8+'><+-.,[]'.index(i)
return r
def num2undecimal(x):
r=''
while x:
r='0123456789 '[x%11]+r
x//=11
return r
def bf2undecimal(x):
return num2undecimal(bf2num(x))

print(bf2undecimal(input()))
```
