Constructs new pseudo-random engine adaptor.

1) Default constructor. The underlying engine is also default-constructed.

2) Constructs the underlying engine with

`s`

.3) Constructs the underlying engine with seed sequence

`seq`

.
This constructor only participate in overload resolution if `Sseq`

qualifies as a `SeedSequence`

. In particular, this constructor does not participate in overload resolution if `Sseq`

is implicitly convertible to `result_type`

.4) Constructs the underlying engine with a copy of

`e`

.5) Move-constructs the underlying engine with

`e`

. `e`

holds unspecified, but valid state afterwards.### [edit] Parameters

s | - | integer value to construct the underlying engine with |

seq | - | seed sequence to construct the underlying engine with |

e | - | pseudo-random number engine to initialize with |
