constexpr

Returns the value clamped between lo and hi.

Parameters

__val	A value of arbitrary type.
__lo	A lower limit of arbitrary type.
__hi	An upper limit of arbitrary type.

Return values

`__lo`	if __val < __lo
`__hi`	if __hi < __val
`__val`	otherwise.

Precondition

_Tp is LessThanComparable and (__hi < __lo) is false.

clamp() [2/2]

template<typename _Tp , typename _Compare >

constexpr const _Tp & std::clamp ( const _Tp &  __val, const _Tp &  __lo, const _Tp &  __hi, _Compare  __comp  )

constexpr

Returns the value clamped between lo and hi.

Parameters

__val	A value of arbitrary type.
__lo	A lower limit of arbitrary type.
__hi	An upper limit of arbitrary type.
__comp	A comparison functor.

Return values

`__lo`	if __comp(__val, __lo)
`__hi`	if __comp(__hi, __val)
`__val`	otherwise.

inplace_merge() [1/2]

template<typename _BidirectionalIterator >

void std::inplace_merge ( _BidirectionalIterator  __first, _BidirectionalIterator  __middle, _BidirectionalIterator  __last  )

inline

Merges two sorted ranges in place.

Parameters

__first	An iterator.
__middle	Another iterator.
__last	Another 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 2550 of file stl_algo.h.

inplace_merge() [2/2]

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

__first	An iterator.
__middle	Another iterator.
__last	Another iterator.
__comp	A 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.

lexicographical_compare() [1/2]

template<typename _II1 , typename _II2 >

constexpr bool std::lexicographical_compare ( _II1  __first1, _II1  __last1, _II2  __first2, _II2  __last2  )

constexpr _RandomAccessIterator std::partial_sort_copy ( _InputIterator  __first, _InputIterator  __last, _RandomAccessIterator  __result_first, _RandomAccessIterator  __result_last  )

inlineconstexpr

Copy the smallest elements of a sequence.

Parameters

__first	An iterator.
__last	Another iterator.
__result_first	A random-access iterator.
__result_last	Another random-access iterator.

Returns

An iterator indicating the end of the resulting sequence.

Copies and sorts the smallest N values from the range [__first,__last) to the range beginning at __result_first, where the number of elements to be copied, N, is the smaller of (__last-__first) and (__result_last-__result_first). After the sort if i and j are iterators in the range [__result_first,__result_first+N) such that i precedes j then *j<*i is false. The value returned is __result_first+N.

partial_sort_copy() [2/2]

template<typename _InputIterator , typename _RandomAccessIterator , typename _Compare >

constexpr _RandomAccessIterator std::partial_sort_copy ( _InputIterator  __first, _InputIterator  __last, _RandomAccessIterator  __result_first, _RandomAccessIterator  __result_last, _Compare  __comp  )

inlineconstexpr

Copy the smallest elements of a sequence using a predicate for comparison.

Parameters

__first	An input iterator.
__last	Another input iterator.
__result_first	A random-access iterator.
__result_last	Another random-access iterator.
__comp	A comparison functor.

Returns

An iterator indicating the end of the resulting sequence.

Copies and sorts the smallest N values from the range [__first,__last) to the range beginning at result_first, where the number of elements to be copied, N, is the smaller of (__last-__first) and (__result_last-__result_first). After the sort if i and j are iterators in the range [__result_first,__result_first+N) such that i precedes j then __comp(*j,*i) is false. The value returned is __result_first+N.

prev_permutation() [1/2]

template<typename _BidirectionalIterator >

constexpr bool std::prev_permutation ( _BidirectionalIterator  __first, _BidirectionalIterator  __last  )

inlineconstexpr

Permute range into the previous dictionary ordering.

Parameters

__first	Start of range.
__last	End of range.

Returns

False if wrapped to last permutation, true otherwise.

Treats all permutations of the range as a set of dictionary sorted sequences. Permutes the current sequence into the previous one of this set. Returns true if there are more sequences to generate. If the sequence is the smallest of the set, the largest is generated and false returned.

prev_permutation() [2/2]

template<typename _BidirectionalIterator , typename _Compare >

constexpr bool std::prev_permutation ( _BidirectionalIterator  __first, _BidirectionalIterator  __last, _Compare  __comp  )

inlineconstexpr

Permute range into the previous dictionary ordering using comparison functor.

Parameters

__first	Start of range.
__last	End of range.
__comp	A comparison functor.

Returns

False if wrapped to last permutation, true otherwise.

Treats all permutations of the range [__first,__last) as a set of dictionary sorted sequences ordered by __comp. Permutes the current sequence into the previous one of this set. Returns true if there are more sequences to generate. If the sequence is the smallest of the set, the largest is generated and false returned.

sort() [1/2]

template<typename _RandomAccessIterator >

constexpr void std::sort ( _RandomAccessIterator  __first, _RandomAccessIterator  __last  )

inlineconstexpr

Sort the elements of a sequence.

Parameters

__first	An iterator.
__last	Another iterator.

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 not preserved, use stable_sort() if this is needed.

sort() [2/2]

template<typename _RandomAccessIterator , typename _Compare >

constexpr void std::sort ( _RandomAccessIterator  __first, _RandomAccessIterator  __last, _Compare  __comp  )

inlineconstexpr

Sort the elements of a sequence using a predicate for comparison.

Parameters

__first	An iterator.
__last	Another iterator.
__comp	A comparison functor.

Returns

Nothing.

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

The relative ordering of equivalent elements is not preserved, use stable_sort() if this is needed.

Definition at line 4841 of file stl_algo.h.

stable_sort() [1/2]

template<typename _RandomAccessIterator >

void std::stable_sort ( _RandomAccessIterator  __first, _RandomAccessIterator  __last  )

inline

Sort the elements of a sequence, preserving the relative order of equivalent elements.

Parameters

__first	An iterator.
__last	Another iterator.

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().

stable_sort() [2/2]

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

__first	An iterator.
__last	Another iterator.
__comp	A 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().
