In a certain code language:

  • 'Great Ghost goes Germany' is written as FOTF4T

  • 'round she goes crazy' is written as ZEHR

  • 'Canada can create ' is written as CAK3X

  • 'Just not good enough' is written as UOOJ

What is the logic behind this code? Why are these phrases encoded in this way?

    $\begingroup$ The main problem with this question is that is in broken English and not using correct terms and that you're not really responding to the questions asked. For example the title is "Coding and Decoding" which suggests it is some cypher for encoding stuff and decoding stuff. However it is seems that this is only for one way encoding with no possible way to get the original back with only the result. So you're not really asking people to decode something but you're asking what function is applied to the sentence to get the resulting code. $\endgroup$ – Ivo Beckers Feb 13 '17 at 14:00

    $\begingroup$ @elavarasan don't panic, this happens to all newbies here. Its part of learning process. Your question made it look like that you were asking for some online ongoing contest so you got many raised brows there :) Have fun learning and don't let this discourage you. $\endgroup$ – Sikorski Feb 13 '17 at 14:24

I don't know what this thing is, but here's what I have found out:

For the 4th, go backwards starting from the $n$th letter of the $n$th word. For the 2nd, go forwards using the same algorithm.

As @Elias points out:

In 1st and 3rd words, the last letter(i.e. letter after the number) is Atbash for the common first letter. (As T is Atbash for G and X is atbash for C). I have no idea about the 1st and the 3rd but those numbers indicate the no.of words containing the first letter common to the sentences +1.(For example 4= 3 words having C as the 1st letter +1)

  • $\begingroup$ The last letter of 1st and 3rd is an atbash for the common first letters. $\endgroup$ – elias Feb 13 '17 at 14:37
  • $\begingroup$ Ah, Yes! That makes much more sense. $\endgroup$ – Sid Feb 13 '17 at 14:40
