The correct word is "Xerxes", not "xerxec". I apologize for the error.

Step 4: Let's continue with the correct word. Spell out the word with numbered positions:

1. X
2. E
3. R
4. X
5. E
6. S

Step 5: Identify the positions of the letter "k".
The letter "k" does not appear in the word.

Step 6: Tally the letters.
R: 1, S: 1, E: 2, X: 2
