Re^2: Palindrome array

Sorry I can't let this stand uncorrected!

  DB<108> @array=1..9
 => (1, 2, 3, 4, 5, 6, 7, 8, 9)
 
  DB<109> @array eq (reverse scalar @array)
 => 1
 
  DB<110> @array=0..9
 => (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
  
  DB<111> @array eq (reverse scalar @array)
 => ""
 
  DB<112> scalar (reverse scalar @array)
 => "01"
 
  DB<113> scalar @array
 => 10

Hi LanX, `> if (@array eq (reverse scalar @array)){..` [download] "..Sorry I can't let this stand uncorrected!.." There is really no need to be sorry, because your assertions and "tests" are so correct and right I. However, I believe Athanasius first caught the message I was trying to pass to the OP, in this line `..The string comparison operator eq puts its operands into scalar context..` ++ LanX I -> Updated. If you tell me, I'll forget. If you show me, I'll remember. if you involve me, I'll understand. --- Author unknown to me	[reply] [d/l]

I must say I agree with the sentiment expressed by LanX: tossing a beginner a lit firecracker and saying "Does this help?" doesn't really help. I sympathize with your desire to show a pathway to an answer rather than just saying the answer, but that one was just a bit too obscure!	[reply]
