Randomly Sorting Strings

[woodyee]

Hi! I'm trying to write a program that will print out a different
string each time it's run from a list of strings.

For example:

example = ['one', 'two', 'three']
# sort them somehow
# 'two' prints out as the output, for example
# run it again and a different string prints out

Make sense? I've tried srand & rand but can't do this with strings. Do
I need to forget the arrays and try something else? I've looked at the
Pickaxe book and Ruby Cookbook but can't find anything. Thanks!

try

example= %w[one two three cat dog cow table]
puts example[rand(example.size)]

Cheers,

try

example= %w[one two three cat dog cow table]
puts example[rand(example.size)]

Another example would be:

example= %w[one two three cat dog cow table].sort_by { rand }
example.each { |string|
puts string
}

that will print all in random order

my regards

I apologize. I didn't read the current quiz.
Does that mean I have to check back with the current quiz when somebody
asks for help in here?

my regards

Another example would be:

example= %w[one two three cat dog cow table].sort_by { rand }
example.each { |string|
puts string
}

You can replace the last three lines with:

puts example

I personally chose to try to avoid to post any material too much
related to
the Quiz and furthermore I point it out to others who might not be
interested in the Quiz.

Overlap happens. No big deal. It just means I chose well for the
quiz topic and it will be helpful in the future.
