Some constraints should be mentioned clearer

  • Given message to encode will not have repeating characters (to preserve unique hash key)

  • Each row will have the same number of letters

3

Could you please clarify? The majority of the cases don’t follow the “constraints” you suggested, e.g.

3
A B C D E F G H I
J K L M N O P Q R
S T U V W X Y Z
HELLOWORLD

In this case:

  • The message to encode, “HELLOWORLD”, contains repeating characters (three Ls).
  • The last row in the grid (“S T U V W X Y Z”) has fewer letters than the others.
4

Ok sorry for the confusion, I meant to say letters in grid must be unique, and this should be mentioned in constraints.

Ignore my 2nd point as I misunderstood that each row must have equal number of letters (which is not the case…)

5

No worries.

I’ve updated the puzzle.
