Replaces the contents of the tuple with the contents of another tuple or a pair.

1) Copy assignment operator. Replaces each element with a copy of the corresponding element of other.

2) Move assignment operator. Replaces each element with the corresponding element of other using move semantics.

3) For all i, assigns std::get<i>(other) to std::get<i>(*this).

4) For all i, assigns std::forward<Ui>(std::get<i>(other)) to std::get<i>(*this).

5) Assigns p.first to the first element of *this and p.second to the second element of *this.

6) Assigns std::forward<U1>(p.first) to the first element of *this and std::forward<U2>(p.second) to the second element of *this.

Parameters

other	-	tuple to replace the contents of this tuple
p	-	pair to replace the contents of this 2-tuple

Return value

*this
