• D (7th) becomes d
• A (8th) remains A
• T (9th) becomes t

The modified word is: iNtImIdAtInG.

Reversing the Word

The word iNtImIdAtInG is arranged in reverse order.

The reversed word is: GnItAdImItNi.

Finding the Target Letter

We need to find the letter that is fifth to the left of the letter sixth from the right in the reversed word GnItAdImItNi.

The length of the reversed word is 12.

1. Identify the letter sixth from the right:

Using 0-based indexing, the index of the Nth letter from the right is $ (Length - N) $. For the 6th letter from the right, the index is $ (12 - 6) = 6 $. The letter at index 6 in GnItAdImItNi is 'I'.

2. Identify the letter fifth to the left of 'I':

The letter 'I' is at index 6. We need the letter 5 positions to its left.

The index of the required letter is $ (Index \ of \ 'I' - 5) $. $ (6 - 5) = 1 $. The letter at index 1 in GnItAdImItNi is 'n'.

Therefore, the required letter is n.
