template<typename _BidirectionalIterator >
void std::inplace_merge ( _BidirectionalIterator  __first,
_BidirectionalIterator  __middle,
_BidirectionalIterator  __last 
)
inline

Merges two sorted ranges in place.

Parameters
__firstAn iterator.
__middleAnother iterator.
__lastAnother iterator.
Returns
Nothing.

Merges two sorted and consecutive ranges, [__first,__middle) and [__middle,__last), and puts the result in [__first,__last). The output will be sorted. The sort is stable, that is, for equivalent elements in the two ranges, elements from the first range will always come before elements from the second.

If enough additional memory is available, this takes (__last-__first)-1 comparisons. Otherwise an NlogN algorithm is used, where N is distance(__first,__last).

Definition at line 2586 of file stl_algo.h.

template<typename _BidirectionalIterator , typename _Compare >
void std::inplace_merge ( _BidirectionalIterator  __first,
_BidirectionalIterator  __middle,
_BidirectionalIterator  __last,
_Compare  __comp 
)
inline

Merges two sorted ranges in place.

Parameters
__firstAn iterator.
__middleAnother iterator.
__lastAnother iterator.
__compA functor to use for comparisons.
Returns
Nothing.

Merges two sorted and consecutive ranges, [__first,__middle) and [middle,last), and puts the result in [__first,__last). The output will be sorted. The sort is stable, that is, for equivalent elements in the two ranges, elements from the first range will always come before elements from the second.

If enough additional memory is available, this takes (__last-__first)-1 comparisons. Otherwise an NlogN algorithm is used, where N is distance(__first,__last).

The comparison function should have the same effects on ordering as the function used for the initial sort.

_ForwardIterator  __last 
)
inline

template<typename _II1 , typename _II2 >
bool std::lexicographical_compare ( _II1  __first1,
_II1  __last1,
_II2  __first2,
_II2  __last2 
)
inline

Performs dictionary comparison on ranges.

Parameters
__first1An input iterator.
__last1An input iterator.
__first2An input iterator.
__last2An input iterator.
Returns
A boolean true or false.

Returns true if the sequence of elements defined by the range [first1,last1) is lexicographically less than the sequence of elements defined by the range [first2,last2). Returns false otherwise. (Quoted from [25.3.8]/1.) If the iterators are all character pointers, then this is an inline call to memcmp.

Returns
Nothing.

Sorts the elements in the range [__first,__last) in ascending order, such that for each iterator i in the range [__first,__last-1), *(i+1)<*i is false.

The relative ordering of equivalent elements is preserved, so any two elements x and y in the range [__first,__last) such that x<y is false and y<x is false will have the same relative ordering after calling stable_sort().

template<typename _RandomAccessIterator , typename _Compare >
void std::stable_sort ( _RandomAccessIterator  __first,
_RandomAccessIterator  __last,
_Compare  __comp 
)
inline

Sort the elements of a sequence using a predicate for comparison, preserving the relative order of equivalent elements.

Parameters
__firstAn iterator.
__lastAnother iterator.
__compA comparison functor.
Returns
Nothing.

Sorts the elements in the range [__first,__last) in ascending order, such that for each iterator i in the range [__first,__last-1), __comp(*(i+1),*i) is false.

The relative ordering of equivalent elements is preserved, so any two elements x and y in the range [__first,__last) such that __comp(x,y) is false and __comp(y,x) is false will have the same relative ordering after calling stable_sort().
