在头文件 <algorithm> 中定义
|
||
template< class RandomIt > void stable_sort( RandomIt first, RandomIt last ); |
(1) | |
template< class RandomIt, class Compare > void stable_sort( RandomIt first, RandomIt last, Compare comp ); |

范围
[first, last)
中的元素进行排序按升序排列。保证保留相等元素的顺序。 operator<的第一个版本使用比较的元素,第二个版本使用给定的比较函数comp
.原文:
Sorts the elements in the range
[first, last)
in ascending order. The order of equal elements is guaranteed to be preserved. The first version uses operator< to compare the elements, the second version uses the given comparison function comp

[编辑] 参数
first, last | - | 范围内的元素进行排序
|
comp | - | comparison function which returns true if the first argument is less than the second. The signature of the comparison function should be equivalent to the following: bool cmp(const Type1 &a, const Type2 &b); The signature does not need to have const &, but the function must not modify the objects passed to it. |
类型要求 | ||
-RandomIt 必须满足 ValueSwappable 和 RandomAccessIterator 的要求。
| ||
-The type of dereferenced RandomIt must meet the requirements of MoveAssignable and MoveConstructible .

[编辑] 返回值
(无)
[编辑] 复杂度
O(N·log2(N)),N = std::distance(first, last)应用
cmp
。如果额外的可用内存,那么复杂O(N·log(N).原文:
O(N·log2(N)), where N = std::distance(first, last) applications of
cmp
. If additional memory is available, then the complexity is O(N·log(N).[编辑] 注释
该函数尝试分配一个临时缓冲区大小相同的顺序进行排序,通常是通过调用std::get_temporary_buffer。如果分配失败,效率低的算法选择.
原文:
This function attempts to allocate a temporary buffer equal in size to the sequence to be sorted, typically by calling std::get_temporary_buffer. If the allocation fails, the less efficient algorithm is chosen.
