Transpose

[Robert Klemme]

This occurred to me while lying sick in bed...

robert@fussel /cygdrive/c/Temp
$ ruby dd.rb
[["foo", "bar", "baz", "biz"], [1, 2, 3, 4], [100, 200, 300, 400]]
[["foo", 1, 100], ["bar", 2, 200], ["baz", 3, 300], ["biz", 4, 400]]

robert@fussel /cygdrive/c/Temp
$ cat dd.rb

require 'enumerator'
require 'pp'

def transpose(a)
a.inject {|aa,b| aa.to_enumzip, b)}.inject([]){|aa,b| aa << b.flatten}
end

a = [
%w{foo bar baz biz},
[1,2,3,4],
[100,200,300,400],
]

pp a, transpose(a)


Did we have this before?

Whatever...
