# Best one liner

## Judges' comments:
### To build:

    make konno

### To run:

    ./konno N
    # where N is 0 to 255

### Try:

    ./konno 30

### Selected Judges Remarks:

This entry is a good one-liner to analyze completely.

For extra credit, what are the minimal changes to convert it to
64-bit integers so that it could print 32 lines?

## Author's comments:
### Remarks

This program outputs [elementary cellular automaton](http://mathworld.wolfram.com/ElementaryCellularAutomaton.html) patterns.

Try:

    ./konno 30
    ./konno 90
    ./konno 102
    ./konno 109
    ./konno 165

There are 256 (from 0 to 255) possible rules.

### Obfuscation

This program uses bit operations. I think

    7&O<<!o>>!o+29

is an intersting operation. This isn't equal to

    7&O>>29

operation. What is the operation doing?

### Limitation

This program assumes that the size of int is 4.
