A simple dummy server to print the request to stdout
#!/usr/bin/env python3
"""
Very simple HTTP server in python.
Usage::
./dummyserve [<port>]
Send a GET request::
curl http://localhost
object Minesweeper extends App {
/*
* Solution to http://codingdojo.org/kata/Minesweeper/ (sort of, doesn't read from stdin)

type Row = Int
type Col = Int
def emptyMap= Map[(Row, Col), Int]().withDefaultValue(0)
val rowLen = 4
⍝ Solution that takes a string which may contain parentheses:
⍝ * Get the maximum depth
⍝ * Check that it is balanced
depths←{+\(1 ¯1 0)['()'⍳⍵]}
balanced←{⌊/depths ⍵}
max_depth←{⌈/depths ⍵}
