Defined in header <algorithm>
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 );	(2)

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.

Original:

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.

参数

first, last	-	范围内的元素进行排序 Original: the range of elements to sort The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions.
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. The types  Type1 and  Type2 must be such that an object of type RandomIt can be dereferenced and then implicitly converted to both of them. ​
Type requirements
- RandomIt must meet the requirements of ValueSwappable and RandomAccessIterator.
- The type of dereferenced RandomIt must meet the requirements of MoveAssignable and MoveConstructible.

复杂性

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).

Original:

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).

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.

Original:

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.
