The Top 3 results from google for Ruby user input integers

*top result stackoverflow

Answer
s = []
for i in 1..3
    puts "What is point " + i.to_s + " ?"    # asks for input
    s.push gets.split(" ").map {|x| x.to_i }
end
if s[1][0] - s[0][0] == 0 # notice the '=='.
    puts 'It worked!'
end

*In second place well sadly the result was stackoverflow again.

For multiple integer input

q = 1
$stdin.readline.split.each {|n| q *= n.to_i }
p q


*result number 3 is drum roll me with this thread http://www.ruby-forum.com/topic/709485

Sadly no decent Ruby Documentation comes up in the google search, even
sader this thread is already in the top 3.
