Deduce the template parameters VALUE, COMPARATOR, and ALLOCATOR from the parameters supplied to the constructor of priority_queue. This deduction guide does not participate if the t_ALLOCATOR parameter does not meet the requirements for a standard allocator or the t_COMPARATOR parameter meets the requirements for a standard allocator.
