Start a loop from 1

Ruby supports a number of ways of counting and looping:

1.upto(10) do |i|
  puts i
end

>> 1.upto(10) do |i|
 >     puts i
|    end #=> 1
1
2

4
5
6
7
8
9
10

There’s also step instead of upto which allows you to increment by a step value:

>> 1.step(10,2) { |i| puts i } #=> 1
1
