Mine in Ruby: file = File.open("millionpi", "r") line = file.gets bigdist = 0 n = 0 a = (0 .. line.length - 1).find_all {|i| line[i,1] == '9'} ##gives the location of each 9 in line for i in 1..a.length - 1 do dist = a[i] - a[i-1] if bigdist < dist bigdist = dist n = a[i-1] end e...

In Ruby: I needed practice opening files so I made 2 of them, vsource (containing the challenge code) and vsource2 (containing the same but with x's removed). file = File.open("vsource", "r") file2 = File.open("vsource2", "r") count = 0 total = 0 line = file.g...

The title gave it all away for me. The pluses before each number along with the Carmen Sandiego reference ('Where in the world is...') made me jump immediately to looking up country codes, and the first three "Turkey Haiti Egypt" (T H E) made me giggle with delight.

Mine in Ruby (which I learned today, be gentle) :P

Code: Select all

x = 0
y = 1
while y < 2119 do
	x = x + y
	#machine to check if whole number
	def whole?(x)
		(x - x.floor) == 0
		end
	z = Math.sqrt(y)
	if whole?(z) == true
		x = x + y
		end
	y = y + 1
	end
puts x

First thing I've written in 5 years, and first time ever using ruby. I could clean this up, but this is what I did to solve: y = ((17**39)**11) y = y.to_s z = 0 x = y[z].chr while x != nil do puts x z = z + 33 x = y[z].chr end Of course, it pops a new number out each line. I know how to clean it now...
