each_with_index
You won’t find each_with_index in the ruby Array class documentation. But this handy little method allows you to iterate through an array while also keeping track of which element you’re on.
It works something like this:
my_array.each_with_index do
|a, index| puts "#{a} is located at index #{index}"
end
Sure beats typing
i=0; i++; i<(array.size -1)
