…art 2 In the Exercise 10 solutions, `allocate(5, res)` was called at the very start of `main`, keeping those 5 qubits reserved during the `aux |= x < 0.5` comparison. Moving the allocation to just before the `control` block lets the synthesizer use res's qubits as auxiliaries for the comparison. The old flow moved this automatically via topological ordering; the new flow does not, so it is done explicitly here. This brings the new-flow width down to 11.

[CLS-8612] Move allocation in Qmod tutorial part 2 (#13)
What
In
Qmod_tutorial_part2.ipynb, the Exercise 10a and 10b solutions allocateres(allocate(5, res)) at the very start ofmain. This reserves those 5 qubits throughout theaux |= x < 0.5comparison, inflating the circuit width in the new synthesis flow.The allocation is moved to just before the
controlblock (right afteraux |= x < 0.5). Sinceresis only first used inside thecontrolblock, this is semantically equivalent, but it now lets the synthesizer reuseres's qubits as auxiliaries for the comparison.The old synthesis flow performed topological ordering and moved this allocation automatically; the new flow does not, so the notebook does it explicitly.
