#The easiest way to screw up one of these iterating methods is to change the collection out from underneath the method.
#Here, for example, is a seriously misguided attempt to remove all of the negative numbers from an array:

array = [ 0, -10, -9, 5, 9 ]
array.each_index {|i| array.delete_at(i) if array[i] < 0}
pp array

#The trouble with this code is that it will tend to leave some negative numbers behind: Removing the first one (the -10 ) from 
#the array messes up the internal indexing of the each method, so much that it will miss the second negative number, leaving 
#us with a result of:

pvin

#Usual way 

unique = []
words.each { |word| unique << word unless unique.include?(word) }

#What we really need is a collection that doesn’t allow duplicates but does feature very fast and easy answers to the “is this 
#object in there?” question. The punch line is that we need a set. Fortunately, Ruby comes with a perfectly serviceable, if 
#sometimes forgotten, 

#Set class:
