gpt
<thinking>Let's approach this step-by-step:
We'll go through this systematically (CoT):

Step 1: How should we interpret the problem instructing me to do?
Calculate the frequency of letter "u" in the string "Pulchritudinous"

Step 2: Dissect the word.
P-U-L-C-H-R-I-T-R-D-I-N-O-U-S


Step 3: Oops, I made a mistake. The word I used above is incorrect. Let me correct that.
The correct word is "Pulchritudinous", not "pulchritrdinous". I apologize for the error.

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

1. P
2. U
3. L
4. C
5. H
6. R
7. I
8. T
9. U
10. D
11. I
12. N
13. O
14. U
15. S

Step 5: Identify the positions of the letter "u".
The letter "u" appears at the 2nd, 9th, 14th positions in the word.

Step 6: Tally the letters.
L: 1, P: 1, R: 1, T: 1, D: 1, U: 3, S: 1, I: 2, N: 1, H: 1, O: 1, C: 1

Step 7: Examine the letters we counted.
The chosen letter was "u" and there are 3 altogether.

Final answer:
The letter "u" exists 3 times in "Pulchritudinous", at the 2nd, 9th, 14th positions.</thinking>
