# Problem D

SMIL

*Siffermaskinen i Lund* (SMIL, “The Number Machine in
Lund”) was a first-generation computer built at Lund
University, in operation from 1956 to 1970. It was based on the
computer architecture developed by John von Neumann at the
Institute of Advanced Studies at Princeton.

Your task is to find the smiles in the memory of SMIL. A
*smile* is sequence of symbols of the form “`:)`”, “`;)`”,
“`:-)`”, or “`;-)`”.

## Input

A single line of at most $2048$ symbols, such as letters from
the English alphabet, digits, space, and many punctuation
marks. (To be precise, the symbols are from the ASCII range
$32$ to $126$.) The line contains at least one
“`:)`”.

## Output

A nonempty sequence of integers, separated by whitespace, of
memory addresses at which a smile appears. The order is not
important. The *address* of a smile is the address of
the “eyes,” i.e., the first symbol. SMIL’s memory addresses are
enumerated $0$,
$1$, $\ldots $, $2047$. The input line starts at
address $0$.

Here is sample input 1:

## Scoring

You receive 1 point for every smile you can find. There are at most 100 smiles.

Your answer is judged *wrong* if it is empty or
contains an address without a smile.
