Re^3: How to warp an array by trading X/Y coordinates (rows/columns)

I'm not working on single characters, but with split I think I can find a suitable delimiter.

I was just being lazy. It works exactly the same for strings provided they do not contain spaces:

C:\test>1157088.pl
[
  ["one", "five", "nine", "thirteen"],
  ["two", "six", "ten", "fourteen"],
  ["three", "seven", "eleven", "fifteen"],
  ["four", "eight", "twelve", "sixteen"],
]

[
  ["one", "two", "three", "four"],
  ["five", "six", "seven", "eight"],
  ["nine", "ten", "eleven", "twelve"],
  ["thirteen", "fourteen", "fifteen", "sixteen"],
]

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority". I knew I was on the right track :)

In the absence of evidence, opinion is indistinguishable from prejudice.
