For loops are not very rubyish. Please use an internal iterator instead.
For example:
(0..5).each { |i| print i }
or
0.upto(5) { |i| print i }
or
6.times { |i| print i }

it show me '012345'.
and then I want to show '543210' and I try.

for i in 5..0
print i
end

it doesn't work :'(.
how can I do it??

5.downto(0) { |i| print i }
