Hello every one.
I am stuck in puzzle ‘hidden word’ for the last test and I would like some help 
We should find : ‘CODNGAME’ and I get : ‘CODNDNGAMEG’ (so 3 extra caracters)
Since letters are displayed from left to right, and then from top to bottom, I can deduce the position (X and Y) of my extra letters.
Here is what I get :
Letter : C at X : 1 and Y : 0
Letter : O at X : 11 and Y : 0
Letter : D at X : 9 and Y : 3
Letter : N at X : 10 and Y : 3
Letter : D at X : 11 and Y : 3
Letter : N at X : 2 and Y : 4
Letter : G at X : 11 and Y : 6
Letter : A at X : 9 and Y : 7
Letter : M at X : 11 and Y : 7
Letter : E at X : 1 and Y : 10
Letter : G at X : 2 and Y : 10
So let’s take the first extra caracter : D, located at (11 ; 3)
Words containing the leter ‘D’ are :
‘FAUCHARDS’
‘GRAUBUNDEN’
‘MEDIUMNITES’
‘ODES’
When I try to manually deduce the matching word, it cannot be a word from the previous list. So, if I am not wrong, this letter should appear in the output, because this letter is not used.
Can you tell me which matching word is associated with with the letter located at (11;3) ?
Many thanks
