But problem says "to 1 byte" or "1 entry" — so perhaps reinterpret as: how many times until size ≤1? Then 10 divisions give 125 >1, 11 give 62.5 — not integer.

- After 9 steps: 64000 / 2⁹ = 64000 / 512 = 125
- After 10 steps: 125 / 2 = 62.5 — not 1.
- So never exactly 1.
- Assume all splits yield integer sizes — so only possible if initial size is power of 2.
- But 64,000 is not — so either error, or compute until size 1 or less, but not exact.
- To fix: change to a power of 2.
