void stable_sort( RandomIt first, RandomIt last, Compare comp );
(2)
昇順で範囲[first, last)内の要素を並べ替えます。等しい要素の順序は保持されることが保証されている。最初のバージョンは、要素を比較するoperator<使用して、2番目のバージョンは、指定された比較関数compを使用しています.
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.

comp - 比較関数. 最初の値が二つ目の値より小さい 場合、 ​trueを返します.

比較関数のシグネチャは以下と同等でなければなりません.

 bool cmp(const Type1 &a, const Type2 &b);

シグネチャはconstを含まなくても構いませんが, 比較関数は渡されたオブジェクトを変更してはなりません.
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. ​

型の要件
-
RandomItValueSwappable and RandomAccessIterator
-
The type of dereferenced RandomIt must meet the requirements of MoveAssignable and MoveConstructible.

O(N·log2(N))N = std::distance(first, last)cmpアプリケーション。追加のメモリが利用可能であれば、複雑さがO(N·log(N)です.
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).

[編集] ノート

この関数は、一般的にstd::get_temporary_bufferを呼び出すことによって、ソートする配列と同じサイズの一時バッファを割り当てようとします。割り当てが失敗した場合は、あまり効率的なアルゴリズムが選ばれ.
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.
