https://codeiq.jp/ace/cielavenir/q431 標準出力に Hello World と出力するプログラムを作成して下さい。ただし、数値、文字及び文字列リテラルを解答に含めることはできません。 Perlのqqやqw、Rubyの%Q、%q、%wなども避けたほうが評価が高くなります。言語仕様をフル活用して下さい！

tokoroten / amidakuji.py

Created June 13, 2013 15:07

アミダクジは公平な仕組みなのかの検証。縦線が10本のアミダクジでは、横線を150本程度ひかないと公平なアミダクジにはなりませんでした。それ以下の場合、当たりがある場所の真上を選択すると当たり確率が高いです。

	#coding:utf-8
	import random

	def amida_shuffle(line_num, exchange_num):
	lines = range(line_num)
	for i in xrange(exchange_num):
	p = random.randrange(line_num - 1)
	lines[p], lines[p+1] = lines[p+1], lines[p]
	return lines
