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.
