Guarded loser/tournament tree.
The smallest element is at the top.
Guarding is done explicitly through one flag _M_sup per element, inf is not needed due to a better initialization routine. This is a well-performing variant.
_Tp | the element type |
_Compare | the comparator to use, defaults to std::less<_Tp> |

The constructor.
__k | The number of sequences to merge. |
__comp | The comparator to use. |

Initializes the sequence "_M_source" with the element "__key".
__key | the element to insert |
__source | __index of the __source __sequence |
__sup | flag that determines whether the value to insert is an explicit __supremum. |
