require 'warray'
# Take an array with values and weight
c=%w(apple 60% orange 30% peach 10%)
# Initialize a Warray object
w = Warray.new(c)
# Build an array with weighted items
puts w.build.to_s
=> ["apple", "apple", "apple", "apple", "apple", "apple", "orange", "orange", "orange", "peach"]
# Warray object size
puts w.size # or w.length
=> 3
# Warray object summarized weight
puts w.wsum
=> 100
# An another example
