# Task
Get the digits sum of `n`th number from the [Look-and-Say sequence](http://en.wikipedia.org/wiki/Look-and-say_sequence)(1-based).

`1, 11, 21, 1211, 111221, 312211, 13112221, 1113213211, ...`

# Input/Output

`[input]` integer `n`

`n`th number in the sequence to get where `1 <= n <= 55`  and `n=1 is "1"`.

[output] an integer

The sum of digits in `n`th number from the `Look-and-Say` sequence.

# Example

For `n = 2`, the output shoule be 2.

`"11" --> 1 + 1 --> 2`

For `n = 3`, the output shoule be 3.

`"21" --> 2 + 1 --> 3`

For `n = 4`, the output shoule be 5.

`"1211" --> 1 + 2 + 1 + 1 --> 5`
